Steps to Calculate GCD of 891, 121, 639, 883 using LCM Formula
Given numbers are 891, 121, 639, 883
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 121) = 9801
GCD(891, 121) = ( 891 x 121 ) / 9801
= 891 / 121
= 891
Step2:
LCM(11, 639) = 7029
GCD(11, 639) = ( 11 x 639 ) / 7029
= 11 / 639
= 11
Step3:
LCM(1, 883) = 883
GCD(1, 883) = ( 1 x 883 ) / 883
= 1 / 883
= 1
So, Greatest Common Divisor of 891, 121, 639, 883 is 1
