Steps to Calculate GCD of 661, 157, 530, 433 using LCM Formula
Given numbers are 661, 157, 530, 433
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 157) = 103777
GCD(661, 157) = ( 661 x 157 ) / 103777
= 661 / 157
= 661
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 433) = 433
GCD(1, 433) = ( 1 x 433 ) / 433
= 1 / 433
= 1
So, Greatest Common Divisor of 661, 157, 530, 433 is 1
