Given numbers are 947, 646, 23, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(947, 646) = 611762
GCD(947, 646) = ( 947 x 646 ) / 611762
= 947 / 646
= 947
Step2:
LCM(1, 23) = 23
GCD(1, 23) = ( 1 x 23 ) / 23
= 1 / 23
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 947, 646, 23, 631 is 1
