Given numbers are 687, 237, 989, 276

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

Apply this formula for all numbers.

Step1:

LCM(687, 237) = 54273

GCD(687, 237) = ( 687 x 237 ) / 54273

= 687 / 237

= 687

Step2:

LCM(3, 989) = 2967

GCD(3, 989) = ( 3 x 989 ) / 2967

= 3 / 989

= 3

Step3:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

So, Greatest Common Divisor of 687, 237, 989, 276 is 1
