We will now calculate the prime factors of 27 and 63, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 27 and 63..

## What is the LCM of 70 and 42?

Least common multiple (LCM) of 42 and 70 is 210.

## What is the prime factorization of 45 and 60?

The prime factorization of 45 is 5 x 3 x 3. The prime factorization of 60 is 2 x 2 x 3 x 5. Therefore the HCF (highest common factor) of these two numbers is the set of factors that appear in both: that’s one 3 and one 5.

## What is the HCF of 45 60 and 75?

15hcf of 45,60 and 75 is 15..

## What is the HCF of 25 and 45?

Greatest common factor (GCF) of 25 and 45 is 5.

## What is the least common multiple of 45 and 60?

180Least common multiple (LCM) of 45 and 60 is 180.

## What are the common factors of 20 and 60?

Answer and Explanation: The GCF of 20 and 60 is 20. To find the GCF, start by identifying the factors of each of the numbers. The factors of 20 are: 1, 2, 4, 5, 10, and…

## What can go into 45?

So, the factors of 45 are 1, 3, 5, 9, 15 and 45.

## Does 61 have any factors?

61 is a prime number. … The exponent of prime number 61 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 61 has exactly 2 factors.

## What is the HCF of 60 and 75?

15The greatest common factor of 60 and 75 is 15.

## What is the HCF of 60?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

## What is the HCF of 20 and 45?
