Given numbers are 156, 195, 415, 676
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 195) = 780
GCD(156, 195) = ( 156 x 195 ) / 780
= 156 / 195
= 156
Step2:
LCM(39, 415) = 16185
GCD(39, 415) = ( 39 x 415 ) / 16185
= 39 / 415
= 39
Step3:
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
= 1 / 676
= 1
So, Greatest Common Divisor of 156, 195, 415, 676 is 1
