Multiples of a given number are always _________
Numbers with only 2 factors are called _________
Numbers having more than 2 factors are called ________
Find 2 common multiples of 10, 15 and 20
Find 2 common multiples of 4, 6 and 12
Find LCM of 45 and 30
Find LCM of 20, 35 and 55
Find LCM of 48, 72 and 108
Find HCF of 24 and 36
Find HCF of 30, 24 and 45
Find HCF of 15, 30 and 90

Answer 1

Answer:

Multiples of a given number are always products

Numbers with only 2 factors are called prime

Numbers having more than 2 factors are called composite

Find 2 common multiples of 10, 15 and 20 = 60 and 20

Find 2 common multiples of 4, 6 and 12 = 24 and 48

Find LCM of 45 and 30 = 90

Find LCM of 20, 35 and 55 = 1540

Find LCM of 48, 72 and 108 = 9828

Find HCF of 24 and 36 = 12

Find HCF of 30, 24 and 45 = 3

Find HCF of 15, 30 and 90 = 15
