Given numbers are 656, 664, 865, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 664) = 54448
GCD(656, 664) = ( 656 x 664 ) / 54448
= 656 / 664
= 656
Step2:
LCM(8, 865) = 6920
GCD(8, 865) = ( 8 x 865 ) / 6920
= 8 / 865
= 8
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 656, 664, 865, 785 is 1
