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
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
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
Four of them.
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
80
80
-360
80 out of 50 = 80/50 = 1.6
We won't be able to find factors of 80 that are not factors of 80. The factors of 80 that aren't factors of 42 are 4, 5, 8, 10, 16, 20, 40 and 80.
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.
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 ■
