GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 987) = 647472
GCD(656, 987) = ( 656 x 987 ) / 647472
= 656 / 987
= 656
Step2:
LCM(1, 700) = 700
GCD(1, 700) = ( 1 x 700 ) / 700
= 1 / 700
= 1
Step3:
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
= 1 / 797
= 1
So, Greatest Common Divisor of 656, 987, 700, 797 is 1
