1-15,25,35
2-165 and 220
​

Answer 1

Answer:

1) Factorization of the following.

15=1×3×5

25=1×5×5

35=1×7×5

Hence, The common factor is 1,5. This implies that

HCF=5

2) The highest common factor of 220 and 88 is 44, because 44 is the highest number that is divisible by both numbers.We found the factors and prime factorization of 220 and 240. The biggest common factor number is the GCF number. So the greatest common factor 220 and 240 is 20

Answer 2

Answer:

1. 105
