Steps to Calculate GCD of 389, 147, 755, 121 using LCM Formula
Given numbers are 389, 147, 755, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 147) = 57183
GCD(389, 147) = ( 389 x 147 ) / 57183
= 389 / 147
= 389
Step2:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 389, 147, 755, 121 is 1
