Answer»

a-8b-4c-5d-6e-12f-11

-8-4-5-6-12-11is the right answer

a)8= 2×4 =2×2×224=2×12 =2×2×6 =2×2×2×332=2×16 =2×2×8 =2×2×2×4 =2×2×2×2×2common factors = 2×2×2=8

b)64=2×32 =2×2×16 =2×2×2×8 =2×2×2×2×4 =2×2×2×2×2×276=2×38 =2×2×19common factors = 2×2 = 4

c) 35=5×715=3×5Common factors = 5d)42=2×21 =2×3×736=2×18 =2×2×9 =2×2×3×3common factors = 2×3 = 6

e)24=2×12 =2×2×6 =2×2×2×336=2×18 =2×2×9 =2×2×3×3common factors = 2×2×3 = 12

f)11=1×1133=3×1188=2×44 =2×2×22 =2×2×2×11comman factors = 11
