GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 472) = 214760
GCD(455, 472) = ( 455 x 472 ) / 214760
= 455 / 472
= 455
Step2:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
Step3:
LCM(1, 758) = 758
GCD(1, 758) = ( 1 x 758 ) / 758
= 1 / 758
= 1
So, Greatest Common Divisor of 455, 472, 256, 758 is 1
