How To Find Multiples & Factors

Multiples:

First five multiples of ‘6’:

1*6=6

2*6=12

3*6=18

Summarize: division by ‘6’ without any remainder = multiple of ‘6’

Example: ‘378’ is/isn’t multiple of ‘6’. 378÷6=63 (63 is whole number), so ‘378’ is multiple of ‘6’

Example: ‘19’ is/isn’t multiple of ‘6’. 19÷6=3 R 1 (there is a remainder), so ‘19’ isn’t a multiple of ‘6’

Factor = Find factor pairs.

28 = 1*28 = 2*14 = 4*7 (1, 28, 2, 14, 4, 7 are all factors of 28)

Conclusion:

Multiple of a certain number ≥ the original number

Factor of a certain number ≤ the original number
