Given numbers are 369, 638, 563, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(369, 638) = 235422
GCD(369, 638) = ( 369 x 638 ) / 235422
= 369 / 638
= 369
Step2:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
Step3:
LCM(1, 255) = 255
GCD(1, 255) = ( 1 x 255 ) / 255
= 1 / 255
= 1
So, Greatest Common Divisor of 369, 638, 563, 255 is 1
