Steps to Calculate GCD of 161, 869, 57, 221 using LCM Formula
Given numbers are 161, 869, 57, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 869) = 139909
GCD(161, 869) = ( 161 x 869 ) / 139909
= 161 / 869
= 161
Step2:
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
= 1 / 57
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 161, 869, 57, 221 is 1
