Steps to Calculate GCD of 289, 661, 403, 139 using LCM Formula
Given numbers are 289, 661, 403, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 661) = 191029
GCD(289, 661) = ( 289 x 661 ) / 191029
= 289 / 661
= 289
Step2:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 289, 661, 403, 139 is 1
