Factor Pairs of 72 example

1. Find Factor Pairs of 72

Solution:

The factor pairs of 72 are pair of numbers, which are multiplied together resulting in 72

The factor pairs of 72 can be either positive pair or negative pair

Positive factor pairs of 72 :

1	`xx`	72	=	72	`=>`	(1, 72)
2	`xx`	36	=	72	`=>`	(2, 36)
3	`xx`	24	=	72	`=>`	(3, 24)
4	`xx`	18	=	72	`=>`	(4, 18)
6	`xx`	12	=	72	`=>`	(6, 12)
8	`xx`	9	=	72	`=>`	(8, 9)
9	`xx`	8	=	72	`=>`	(9, 8)

Since `9` and `8` are already factors of `72`, so we stop here

Hence, Positive factor pairs of 72 are
`(1, 72),(2, 36),(3, 24),(4, 18),(6, 12),(8, 9)`

Negative factor pairs of 72 :

-1	`xx`	-72	=	72	`=>`	(-1, -72)
-2	`xx`	-36	=	72	`=>`	(-2, -36)
-3	`xx`	-24	=	72	`=>`	(-3, -24)
-4	`xx`	-18	=	72	`=>`	(-4, -18)
-6	`xx`	-12	=	72	`=>`	(-6, -12)
-8	`xx`	-9	=	72	`=>`	(-8, -9)
-9	`xx`	-8	=	72	`=>`	(-9, -8)

Since `-9` and `-8` are already factors of `72`, so we stop here

Hence, Negative factor pairs of 72 are
`(-1, -72),(-2, -36),(-3, -24),(-4, -18),(-6, -12),(-8, -9)`
