Oh, dude, the Highest Common Factor (HCF) of 28, 14, and 21 is 7. You just gotta find the largest number that divides evenly into all three of those numbers. It's like finding the VIP guest that gets into all the parties without any hassle.
Well, well, well, look who's trying to be a math whiz! The Highest Common Factor (HCF) of 28, 14, and 21 is 7. So, there you have it, darling. Keep those numbers in check and you'll be just fine.
7
The GCF is 14.
84 and 14, respectively.
The Highest Common Factor (HCF) of 21, 77, and 84 is 7. To find the HCF, you need to identify the common factors of the numbers and determine the highest one they all share. In this case, the factors of 21 are 1, 3, 7, 21; the factors of 77 are 1, 7, 11, 77; and the factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. The highest common factor among them is 7.
The Highest Common Factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 168 and 252, we first list the factors of each number: 168 (1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168) and 252 (1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252). The common factors are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. Therefore, the HCF of 168 and 252 is 84.
