Steps to Calculate GCD of 161, 139, 35, 669 using LCM Formula
Given numbers are 161, 139, 35, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 139) = 22379
GCD(161, 139) = ( 161 x 139 ) / 22379
= 161 / 139
= 161
Step2:
LCM(1, 35) = 35
GCD(1, 35) = ( 1 x 35 ) / 35
= 1 / 35
= 1
Step3:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
So, Greatest Common Divisor of 161, 139, 35, 669 is 1
