Four of them.
LCM of (a) and (b) is given as (ab)/(GCF(a,b)) To find the GCF, factor and find common factors. 50 factors to [2 5 5] 80 factors to [2 2 2 2 5] Common factors are [2 5] = 10 50 * 80 / 10 = 400 ■
Since 40 is a factor of 80, all of its factors are common.
80
The GCF is 10.
the ans iz 20
1, 2, 5 and 10
The factors of 50 are: 1, 2, 5, 10, 25, 50The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80The common factors are: 1, 2, 5, 10
Answer: 10Explination: These are the common factors--80-1,2,4,5,8,10,16,20,4050-1,2,5,10,25So the greatest common factor is 10.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 Factors of 62: 1, 2, 31, 62 Factors of 50: 1, 2, 5, 10, 25, 50 GCF (80, 62, 50) = 2
LCM of (a) and (b) is given as (ab)/(GCF(a,b)) To find the GCF, factor and find common factors. 50 factors to [2 5 5] 80 factors to [2 2 2 2 5] Common factors are [2 5] = 10 50 * 80 / 10 = 400 ■
The common factors of 55 and 80 are 1 and 5
The factors of 50 are: 1, 2, 5, 10, 25, 50 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The common factors of 36 and 80 are: 1, 2, and 4
The common factors of 68 and 80 are 1, 2 and 4.
The greatest common factor of 80 and 50 is 10 :)
The common factors are: 1, 5
50 is not a prime number because it has more than 2 factors 10x5=50 1x50=50 and 80 is also not a prime because it has more than 2 factors 1x80=80 2x40= 80
