Given numbers are 656, 389, 433, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 389) = 255184
GCD(656, 389) = ( 656 x 389 ) / 255184
= 656 / 389
= 656
Step2:
LCM(1, 433) = 433
GCD(1, 433) = ( 1 x 433 ) / 433
= 1 / 433
= 1
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 656, 389, 433, 245 is 1
