156: Hcf of 13 and 39= 13 13*12=156 =156
HCF = 3... LCM = 18 !
The HCF of 39 and 20 is 1
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 3.
The GCF is 18.
