Steps to Calculate GCD of 669, 371, 646, 121 using LCM Formula
Given numbers are 669, 371, 646, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 371) = 248199
GCD(669, 371) = ( 669 x 371 ) / 248199
= 669 / 371
= 669
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 669, 371, 646, 121 is 1
