GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 404) = 128876
GCD(638, 404) = ( 638 x 404 ) / 128876
= 638 / 404
= 638
Step2:
LCM(2, 575) = 1150
GCD(2, 575) = ( 2 x 575 ) / 1150
= 2 / 575
= 2
Step3:
LCM(1, 880) = 880
GCD(1, 880) = ( 1 x 880 ) / 880
= 1 / 880
= 1
So, Greatest Common Divisor of 638, 404, 575, 880 is 1
