Given numbers are 687, 213, 535, 638

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

Apply this formula for all numbers.

Step1:

LCM(687, 213) = 48777

GCD(687, 213) = ( 687 x 213 ) / 48777

= 687 / 213

= 687

Step2:

LCM(3, 535) = 1605

GCD(3, 535) = ( 3 x 535 ) / 1605

= 3 / 535

= 3

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 687, 213, 535, 638 is 1
