HCF of 650 and 1170 by Long Division
HCF of 650 and 1170 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
 Step 1: Divide 1170 (larger number) by 650 (smaller number).
 Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (650) by the remainder (520).
 Step 3: Repeat this process until the remainder = 0.
The corresponding divisor (130) is the HCF of 650 and 1170.

There are 8 common factors of 650 and 1170, that are 65, 1, 2, 130, 5, 10, 13, and 26. Therefore, the highest common factor of 650 and 1170 is 130.
HCF of 650 and 1170 by Euclidean Algorithm
As per the Euclidean Algorithm, HCF(X, Y) = HCF(Y, X mod Y)
where X > Y and mod is the modulo operator.
Here X = 1170 and Y = 650
 HCF(1170, 650) = HCF(650, 1170 mod 650) = HCF(650, 520)
 HCF(650, 520) = HCF(520, 650 mod 520) = HCF(520, 130)
 HCF(520, 130) = HCF(130, 520 mod 130) = HCF(130, 0)
 HCF(130, 0) = 130 (∵ HCF(X, 0) = X, where X ≠ 0)
Therefore, the value of HCF of 650 and 1170 is 130.
