Given numbers are 156, 815, 679, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 815) = 127140
GCD(156, 815) = ( 156 x 815 ) / 127140
= 156 / 815
= 156
Step2:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 156, 815, 679, 129 is 1
