Steps to Calculate GCD of 873, 855, 549, 121 using LCM Formula
Given numbers are 873, 855, 549, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(873, 855) = 82935
GCD(873, 855) = ( 873 x 855 ) / 82935
= 873 / 855
= 873
Step2:
LCM(9, 549) = 549
GCD(9, 549) = ( 9 x 549 ) / 549
= 9 / 549
= 9
Step3:
LCM(9, 121) = 1089
GCD(9, 121) = ( 9 x 121 ) / 1089
= 9 / 121
= 9
So, Greatest Common Divisor of 873, 855, 549, 121 is 1
