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.
Since 8 is a factor of 24, it is automatically the GCF of this problem.
If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised. If there is no common factor then the polynomial cannot be factorised.
By finding the factors in both numbers and then finding the one that is greatest in common. For example the G.C.F for 45 and 36 is 9.
The Greatest Common Factor (GCF) is: 6
The Greatest Common Factor (GCF) is: 1
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
in what kind of problem?
21 and 84
Since 8 is a factor of 24, it is automatically the GCF of this problem.
The greatest common multiple is an infinite amount and not very practical for problem solving.
Since 45 is a factor of 270, it is automatically the GCF.
Since 16 is a factor of 80, it is automatically the GCF of this problem.
Since 34 is a factor of 170, it is automatically the GCF of this problem.
Since 49 is a factor of 147, it is automatically the GCF of this problem.
Since 315 is a factor of 1575, it is automatically the GCF of this problem.
Since 30 is a factor of 210, it is automatically the GCF of this problem.
Since 32 is a factor of 64, it is automatically the GCF of this problem.
