Given numbers are 688, 243, 287, 979

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

Apply this formula for all numbers.

Step1:

LCM(688, 243) = 167184

GCD(688, 243) = ( 688 x 243 ) / 167184

= 688 / 243

= 688

Step2:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 688, 243, 287, 979 is 1
