GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 775) = 48825
GCD(315, 775) = ( 315 x 775 ) / 48825
= 315 / 775
= 315
Step2:
LCM(5, 877) = 4385
GCD(5, 877) = ( 5 x 877 ) / 4385
= 5 / 877
= 5
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 315, 775, 877, 638 is 1
