GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 472) = 48144
GCD(816, 472) = ( 816 x 472 ) / 48144
= 816 / 472
= 816
Step2:
LCM(8, 970) = 3880
GCD(8, 970) = ( 8 x 970 ) / 3880
= 8 / 970
= 8
Step3:
LCM(2, 664) = 664
GCD(2, 664) = ( 2 x 664 ) / 664
= 2 / 664
= 2
So, Greatest Common Divisor of 816, 472, 970, 664 is 2
