Given numbers are 815, 156, 970, 317
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 156) = 127140
GCD(815, 156) = ( 815 x 156 ) / 127140
= 815 / 156
= 815
Step2:
LCM(1, 970) = 970
GCD(1, 970) = ( 1 x 970 ) / 970
= 1 / 970
= 1
Step3:
LCM(1, 317) = 317
GCD(1, 317) = ( 1 x 317 ) / 317
= 1 / 317
= 1
So, Greatest Common Divisor of 815, 156, 970, 317 is 1
