HCF of 36 and 54 and 72?

Answer 1

The HCF (highest common factor) is found by splitting each number into its prime factors:

• 36 = 2 x 2 x 3 x 3
• 54 = 2 x 3 x 3 x 3
• 72 = 2 x 2 x 2 x 3 x 3

The HCF is then found by mulitplying together the factors that are common to each number:

2 x 3 x 3 = 18

(Because there is only one 2 in 54, only one 2 can be used. The same applies with the number o 3's. There are only two in each number so only 2 can be used).

Answer 2

To find the Highest Common Factor (HCF) of 36, 54, and 72, we need to first find the factors of each number. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The HCF is the greatest number that is a factor of all three numbers, which in this case is 18.

Answer 3

Well, darling, the Highest Common Factor (HCF) of 36, 54, and 72 is 18. It's like finding the diva that rules them all in this mathematical circus. So, grab your calculator and bow down to the queen of factors, 18.

Answer 4

Oh, dude, the Highest Common Factor (HCF) of 36, 54, and 72 is 18. It's like the biggest number that can divide all of them without leaving a remainder. So yeah, 18 is the HCF here, like no big deal.
