Given numbers are 638, 863, 558, 995

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(638, 863) = 550594

GCD(638, 863) = ( 638 x 863 ) / 550594

= 638 / 863

= 638

Step2:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

Step3:

LCM(1, 995) = 995

GCD(1, 995) = ( 1 x 995 ) / 995

= 1 / 995

= 1

So, Greatest Common Divisor of 638, 863, 558, 995 is 1
