The GCF is 21.
The GCF is 14.
The Highest Common Factor (HCF) of 90 and 126 is the largest number that divides both 90 and 126 without leaving a remainder. To find the HCF, we need to determine the common factors of 90 and 126, which are 1, 2, 3, 6, 9, and 18. The largest number among these common factors is 18. Therefore, the HCF of 90 and 126 is 18.
The LCM is: 126
The HCF is 9
The GCF is 18.
The HCF is: 7
hcf(18, 30) = 6.
The HCF of 30 and 105 is 15.
The GCF is 30.
The Highest Common Factor is 126
Oh, dude, the greatest common factor of those numbers is like the biggest number that can divide all of them without leaving a remainder. So, you just gotta find the factors of each number and see which one they all have in common. It's like a math puzzle, but not as fun as a jigsaw puzzle. So, the greatest common factor of 84, 126, 294, and 462 is 42.
