Given numbers are 638, 257, 454, 264
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 257) = 163966
GCD(638, 257) = ( 638 x 257 ) / 163966
= 638 / 257
= 638
Step2:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
Step3:
LCM(1, 264) = 264
GCD(1, 264) = ( 1 x 264 ) / 264
= 1 / 264
= 1
So, Greatest Common Divisor of 638, 257, 454, 264 is 1
