Given numbers are 317, 639, 156, 274
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(317, 639) = 202563
GCD(317, 639) = ( 317 x 639 ) / 202563
= 317 / 639
= 317
Step2:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
Step3:
LCM(1, 274) = 274
GCD(1, 274) = ( 1 x 274 ) / 274
= 1 / 274
= 1
So, Greatest Common Divisor of 317, 639, 156, 274 is 1
