WORKSHEET:MULTIPLES AND FACTORS - SOLUTION EXERCISE 5


5)Find the HCF (Highest Common Factor) and the LCM (Lowest Common Multiple)
of each pair of numbers:
<
a) 10 and 16
10 = 2 x 5

HCF = 2
b) 49 and 77

77 = 7 x 11
HCF = 7
c) 200 and 300





d) 450 and 600



e) 72 and 270



f) 22 and 121
22 = 2 x 11

HCF = 11
LCM = 121 x 2 = 242
