Given numbers are 670, 638, 875, 687

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

Apply this formula for all numbers.

Step1:

LCM(670, 638) = 213730

GCD(670, 638) = ( 670 x 638 ) / 213730

= 670 / 638

= 670

Step2:

LCM(2, 875) = 1750

GCD(2, 875) = ( 2 x 875 ) / 1750

= 2 / 875

= 2

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 670, 638, 875, 687 is 1
