Given numbers are 816, 128, 720, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 128) = 6528
GCD(816, 128) = ( 816 x 128 ) / 6528
= 816 / 128
= 816
Step2:
LCM(16, 720) = 720
GCD(16, 720) = ( 16 x 720 ) / 720
= 16 / 720
= 16
Step3:
LCM(16, 392) = 784
GCD(16, 392) = ( 16 x 392 ) / 784
= 16 / 392
= 16
So, Greatest Common Divisor of 816, 128, 720, 392 is 8
