Steps to Calculate GCD of 178, 530, 989, 136 using LCM Formula
Given numbers are 178, 530, 989, 136
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(178, 530) = 47170
GCD(178, 530) = ( 178 x 530 ) / 47170
= 178 / 530
= 178
Step2:
LCM(2, 989) = 1978
GCD(2, 989) = ( 2 x 989 ) / 1978
= 2 / 989
= 2
Step3:
LCM(1, 136) = 136
GCD(1, 136) = ( 1 x 136 ) / 136
= 1 / 136
= 1
So, Greatest Common Divisor of 178, 530, 989, 136 is 1
