How do you find out the prime factors of 42?
42 Divide by two. 21,2 Divide by three. 7,3,2 Stop.
What are the common factors of 42 and 52?
Method to find common factors: Step 1: Find the difference between the two numbers. 52 - 42 = 10. Step 2: Find the factors of the difference so obtained. Factors of 10 are 1, 2, 5 and 10. Step 3: Check with only factors. 1 is factor of every number so, 1 is one of the common factors. 42 and 52 both are even numbers so, 2 is also the common factor. Numbers ending with the digit either 5 or 0 are only divisible by 5. And the ones ending with only 0 are divisible by 10. Clearly 42 and 52 are not divisible by 5 and 10. So, the only common factors of 42 and 52 are 1 and 2.
What are the difference between multiples of 42 and the factors of 42?

How do i tell difference between a 318 or 360?
to find the difference between two numbers is to subtract the smaller one from the bigger one, that's 360 - 318 = 42 the difference between 318 and 360 is 42.
What is the greatest common factor of 49 and 42?
One way to approach this is to look at the difference between 42 and 49, which is 7. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 42 and 49 are divisible by 7, the greatest common factor is 7. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 49 are 1, 7, and 49. The common factors are 1 and 7. Therefore, the greatest common factor is 7. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 42 are 2, 3, and 7. The prime factors of 49 are 7 and 7. The prime factors in common are a single 7, so the greatest common factor is 7
How do you find the prime factors of 42?

Two common factors of 42 and 231?
All the common factors of 42 and 231 are: 1, 3, 7, 21.
What are the highest common factors of 42?
1, 2, 3, 6, 7, 14, 21, and 42 are the factors of 42. You need another set of factors to compare them to to find something in common.
What are the common factors of 42?
There cannot be a common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
