Given numbers are 981, 688, 487

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

Apply this formula for all numbers.

Step1:

LCM(981, 688) = 674928

GCD(981, 688) = ( 981 x 688 ) / 674928

= 981 / 688

= 981

Step2:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 981, 688, 487 is 1
