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 GCF is 30.
HCF(160, 90) = 10.
Factors of 24: 1,2,3,4,6,8,12 and 24. Factors of 90: 1,2,3,5,9,10,18,30,45 and 90. The HCF (highest common factor) is 3.
The hcf is 15.
