Given numbers are 687, 784, 813, 377

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

Apply this formula for all numbers.

Step1:

LCM(687, 784) = 538608

GCD(687, 784) = ( 687 x 784 ) / 538608

= 687 / 784

= 687

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

So, Greatest Common Divisor of 687, 784, 813, 377 is 1
