The GCF for 24 56 120 is 8.
24, because (.20)(120)=24.
24
For 13/24 and 7/15 the common denominator is 120. So we have: (13 x 5)/(24 x 5) and (7 x 8)/(15 x 8) 65/120 and 56/120 (which are equivalent respectively to 13/24 and 7/15). Since 65/120 > 56/120, so is 13/24 > 7/15.
The HCF is 24, so both numbers will have 24 as a factor. This means both will be multiples of 24 so we can simply divide 144 by 24 to find which multiple. Do this and you get: 144/24 = 6 So the number multiple of 24 each number is needs to add up to 6. However, it cannot be 3 and 3 or 2 and 4 as then the numbers would have a greater HCF. Thus it must be 5x24 and 1x24, or 24 and 120.
The pattern is x1, x2, x3, x4, x5, x6.... The next two numbers are 120, 720.

720 5,040 multiply previous number by 2 3 4 5 then 6 7
120. The numbers are factorials: 1, 1x2, 1x2x3, etc.
To find two numbers that multiply to make -720, one of the numbers must be negative while the other is positive. For example, -24 and 30 multiply to give -720, since (-24) × 30 = -720. There are many other pairs as well, such as -36 and 20 or -18 and 40.
24 x 30 = 720 720
2*3*5*24 is one possible set.
720 = 24 x 32 x 5
