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 out of 50 = 80/50 = 1.6
80
-360
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.
50% of £80 = £40 = 50% * £80 = 50%/100% * £80 = £40
