Steps to Calculate GCD of 207, 778, 415, 139 using LCM Formula
Given numbers are 207, 778, 415, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 778) = 161046
GCD(207, 778) = ( 207 x 778 ) / 161046
= 207 / 778
= 207
Step2:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 207, 778, 415, 139 is 1
