Given numbers are 972, 663, 930, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(972, 663) = 214812
GCD(972, 663) = ( 972 x 663 ) / 214812
= 972 / 663
= 972
Step2:
LCM(3, 930) = 930
GCD(3, 930) = ( 3 x 930 ) / 930
= 3 / 930
= 3
Step3:
LCM(3, 680) = 2040
GCD(3, 680) = ( 3 x 680 ) / 2040
= 3 / 680
= 3
So, Greatest Common Divisor of 972, 663, 930, 680 is 1
