Given numbers are 638, 708, 879, 494

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

Apply this formula for all numbers.

Step1:

LCM(638, 708) = 225852

GCD(638, 708) = ( 638 x 708 ) / 225852

= 638 / 708

= 638

Step2:

LCM(2, 879) = 1758

GCD(2, 879) = ( 2 x 879 ) / 1758

= 2 / 879

= 2

Step3:

LCM(1, 494) = 494

GCD(1, 494) = ( 1 x 494 ) / 494

= 1 / 494

= 1

So, Greatest Common Divisor of 638, 708, 879, 494 is 1
