The HCF and LCM of two numbers are 20 and 120.if one of the numbers is 40.the second number is?
To find the second number, you can use the relationship between the HCF, LCM, and numbers themselves.
Let's first identify the relationship between the numbers, the HCF, and the LCM:
The product of two numbers is equal to the product of their HCF and LCM. Let's denote the two numbers as a and b, the HCF as h, and the LCM as l. Given that the HCF and LCM of two numbers are 20 and 120 respectively, and one of the numbers is 40, we can use the relationship mentioned above to solve for the second number.
We know that: a * b = h * l 40 * b = 20 * 120 40b = 2400 b = 2400 / 40 b = 60
Therefore, the second number is 60.
if the prime factors of a number are all the the prime numbers less than 7 with no factor repeated,then this number is equal to:
If the prime factors of a number are all the prime numbers less than 7 with no factor repeated, then this number can be found by multiplying these prime numbers together. The prime numbers less than 7 are 2, 3, and 5.
So, the number is equal to: 2 * 3 * 5 = 30
Therefore, the number is equal to 30.
what is prime fator?
A prime factor is a prime number that can be multiplied together with other prime factors to produce the original number. In other words, it is a prime number that divides the original number exactly without leaving a remainder. For example, the prime factors of 12 are 2 and 3, because 2 * 2 * 3 = 12, and 2 and 3 are both prime numbers.
The HCF and LCM of 2700 and 3000 respectively are equal to ?
The highest common factor (HCF) and the least common multiple (LCM) of 2700 and 3000 can be calculated as follows:
First, let's find the prime factorization of both numbers: 2700 = 2^2 * 3^3 * 5^2 3000 = 2^3 * 3 * 5^3
The HCF is calculated by taking the product of the lowest powers of common prime factors: HCF = 2^2 * 3^1 * 5^2 HCF = 4 * *25 HCF = 300
The LCM is calculated by taking the product of the highest powers of all prime factors: LCM = 2^3 * 3^3 * 5^3 LCM = 8 * 27 * 125 LCM = 27000
Therefore, the HCF of 2700 and 3000 is 300, and the LCM is 27000.
The Product of two numbers is 4200.if the cf OF THE NUMBERS IS 10.Then the LCM of the numbers is equal to?
Given: Product of the two numbers = 4200 Common Factor (HCF) of the numbers = 10
We can use the relationship between the HCF, LCM, and the product of the numbers to find the LCM.
The product of two numbers = HCF * LCM 4200 = 10 * LCM LCM = 4200 / 10 LCM = 420
Therefore, the LCM of the two numbers is 420.
