Given numbers are 655, 638, 569, 480
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 638) = 417890
GCD(655, 638) = ( 655 x 638 ) / 417890
= 655 / 638
= 655
Step2:
LCM(1, 569) = 569
GCD(1, 569) = ( 1 x 569 ) / 569
= 1 / 569
= 1
Step3:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
So, Greatest Common Divisor of 655, 638, 569, 480 is 1
