24
The HCF of 48 and 72 is 24. The LCM is 144.
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 answer is: 24 You do this for working out..... 120= 2x2x2x3x5 144= 2x2x2x2x3x3 2 2 2 3 are the same numbers so times them together.....24!
The HCF is 18
