Answer 1

Step-by-step explanation:

1. common factor of 20

Answer = 2,4,5,10,20

1. 28×2=56
2. 36×= 72
3. 56+72= 812
4. Answer =812

1. ex=3.6
2. 30.42 =2,3,5,6, 10,30,=42=2,6,14,42
3. 18.60=2,3,8,18,=60=2,6,10,12,15,20,30,60
4. Answer HCF=42,60

1. 36,48
2. 36=2,4,6,9,12,18,36
3. 48=2,6,12,28,48
4. 34=2,17,34,
5. 102=2,17,34,102

Answer=HCF=36,48,34,102

Lot=70= 2,7,10,14,35,70

105=15,21,35,105

175=25,35,175

answer=HCF= 70,105,175
