Given numbers are 638, 840, 886, 470

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

Apply this formula for all numbers.

Step1:

LCM(638, 840) = 267960

GCD(638, 840) = ( 638 x 840 ) / 267960

= 638 / 840

= 638

Step2:

LCM(2, 886) = 886

GCD(2, 886) = ( 2 x 886 ) / 886

= 2 / 886

= 2

Step3:

LCM(2, 470) = 470

GCD(2, 470) = ( 2 x 470 ) / 470

= 2 / 470

= 2

So, Greatest Common Divisor of 638, 840, 886, 470 is 2
