Given numbers are 687, 715, 438, 633

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

Apply this formula for all numbers.

Step1:

LCM(687, 715) = 491205

GCD(687, 715) = ( 687 x 715 ) / 491205

= 687 / 715

= 687

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

Step3:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

So, Greatest Common Divisor of 687, 715, 438, 633 is 1
