Given numbers are 638, 291, 851, 887

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

Apply this formula for all numbers.

Step1:

LCM(638, 291) = 185658

GCD(638, 291) = ( 638 x 291 ) / 185658

= 638 / 291

= 638

Step2:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 638, 291, 851, 887 is 1
