It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
1 is a factor of every nonzero number, so 42 would have it in common with any other number.
Find the highest factor of the smallest of the numbers and divide it into the highest number, if it goes in exactly that's your answer?
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and 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 63 are 1, 3, 7, 9, 21, and 63. The common factors are 1, 3, 7, and 21.
You write down all of both number's factors and find the biggest number that they share. or Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF
Find the prime factorization. It doesn't matter if you use a factor tree, or rainbow or firework. For example: 42 42 21,2 3,7,2 The prime factorization of 42 is 2 x 3 x 7. The greatest prime factor is 7.
42 21,2 7,3,2
42 21,2 7,3,2
Yes, 42 has 2 as a factor.
42 21,2 7,3,2
No, 5 is not a factor of 42. A factor of a number divides it evenly with no remainder. When you divide 42 by 5, it does not divide evenly and leaves a remainder of 2. Therefore, 5 is not a factor of 42.
3 is a factor of 42 but 3 is a prime number
You need at least two numbers to find a GCF.
The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
1,2,3,6,7,14,21,42
To find the first multiple of 6 that has 7 as a factor, we need to find the least common multiple (LCM) of 6 and 7. The LCM of 6 and 7 is 42. Therefore, the first multiple of 6 that has 7 as a factor is 42.
Divide the product by the factor you have. 6 x ? = 42 42 ÷ 6 = 7
