Given numbers are 560, 810, 674, 638

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

Apply this formula for all numbers.

Step1:

LCM(560, 810) = 45360

GCD(560, 810) = ( 560 x 810 ) / 45360

= 560 / 810

= 560

Step2:

LCM(10, 674) = 3370

GCD(10, 674) = ( 10 x 674 ) / 3370

= 10 / 674

= 10

Step3:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

So, Greatest Common Divisor of 560, 810, 674, 638 is 2
