1, 639 Then by inspection of the number 639 , we note that each number is a multiple of '3' . So '3' is a factor. Also , slightly more 'tricky'. If we add the digits of 639 ; 6 + 3 + 9 = 18 1 + 8 = 9 . This means that the number has '9' is a factor. NB This only applies to factors/multiples of '9' Finally, divide 639 by 71 and/or 213 . If you have a whole number answer (No decimals), then those numbers are also factors of 639. Hence 639/71 = 9 & 329 / 213 = 3 So allthe given numbers are factors of 639.
