GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 506) = 211002
GCD(417, 506) = ( 417 x 506 ) / 211002
= 417 / 506
= 417
Step2:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
Step3:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
So, Greatest Common Divisor of 417, 506, 989, 256 is 1
