The greatest common factor of 42 depends upon the other numbers with which 42 has COMMON factors. However, the greatest common factor HAS to be one of the factors of 42 which are: 1, 2, 3, 6, 7, 14, 21, 42.
The GCF is what goes into the numbers, the LCM is what the numbers go into. 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 Combine the factors, eliminating duplicates. 2 x 3 x 5 x 7 = 210, the LCM.
The positive whole-number factors of 42 are: 1, 2, 3, 6, 7, 14, 21, and 42.
The lowest common multiple - is 42 !
Their lowest common multiple is 378
To reduce any fraction to its lowest terms, divide the numeratorand the denominator by their greatest common factor.You have 36/54.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The common factors are 1, 2, 3, 6, 9, and 18.The greatest common factor is 18 .36 / 18 = 254 / 18 = 336/54 = 2/3Note:That's why you had to spend all that time doing common factors andgreatest common factor before you could go on to doing fractions.
The common factors are: 1, 7
The GCF is 42.
The greatest common factor is the highest number that divides exactly into two or more numbers.42: 1, 2, 3, 6, 7, 14, 21, 4298: 1, 2, 7, 14, 49, 98The GCF of 42 and 98 is 14.If you're not a good guesser the best way to go about doing this is to list all the factors of each number, like so:42-- 98--1 12 23 76 147142142Well, I did not list all the factors of 98, but I know that since 98 is not divisible by 21 or 42 that the greatest common factor is 14.Answer: 14
When you find a greatest common factor, or GCF, you find all the factors that go into a number. Lets try it with 8 and 12. Factors of 8: 1, 8, 2, 4 Factors of 12: 1, 12, 2, 6 3, 4 The factors that were the same are the common factors. For problem, they were 1, 2, and 4. The greatest was 4. That's the GCF for that problem. Hope this helped!
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
Factors go into numbers, numbers go into multiples. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42 Multiples of 42: 42, 84, 126 and so on.
You need at least two numbers to find a GCF.
Answer = 2Greatest common factor is largest number 20 or below they both go into evenly
The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. Factors go into numbers, numbers go into multiples.
1. There are no other common factors (noticed because 23 is prime and doesn't go into 50)
It is: 6
1344 is a multiple of 42. 42 is a factor of 1344. Factors go into numbers, numbers go into multiples.
