Given numbers are 657, 638, 569, 175
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 638) = 419166
GCD(657, 638) = ( 657 x 638 ) / 419166
= 657 / 638
= 657
Step2:
LCM(1, 569) = 569
GCD(1, 569) = ( 1 x 569 ) / 569
= 1 / 569
= 1
Step3:
LCM(1, 175) = 175
GCD(1, 175) = ( 1 x 175 ) / 175
= 1 / 175
= 1
So, Greatest Common Divisor of 657, 638, 569, 175 is 1
