Given numbers are 687, 813, 263, 356

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

Apply this formula for all numbers.

Step1:

LCM(687, 813) = 186177

GCD(687, 813) = ( 687 x 813 ) / 186177

= 687 / 813

= 687

Step2:

LCM(3, 263) = 789

GCD(3, 263) = ( 3 x 263 ) / 789

= 3 / 263

= 3

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 687, 813, 263, 356 is 1
