Given numbers are 656, 509, 466, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 509) = 333904
GCD(656, 509) = ( 656 x 509 ) / 333904
= 656 / 509
= 656
Step2:
LCM(1, 466) = 466
GCD(1, 466) = ( 1 x 466 ) / 466
= 1 / 466
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 656, 509, 466, 438 is 1
