GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 897) = 588432
GCD(656, 897) = ( 656 x 897 ) / 588432
= 656 / 897
= 656
Step2:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
Step3:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
So, Greatest Common Divisor of 656, 897, 497, 440 is 1
