Given numbers are 687, 958, 309, 948

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

Apply this formula for all numbers.

Step1:

LCM(687, 958) = 658146

GCD(687, 958) = ( 687 x 958 ) / 658146

= 687 / 958

= 687

Step2:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

Step3:

LCM(1, 948) = 948

GCD(1, 948) = ( 1 x 948 ) / 948

= 1 / 948

= 1

So, Greatest Common Divisor of 687, 958, 309, 948 is 1
