Given numbers are 987, 131, 689, 683

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

Apply this formula for all numbers.

Step1:

LCM(987, 131) = 129297

GCD(987, 131) = ( 987 x 131 ) / 129297

= 987 / 131

= 987

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

Step3:

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

= 1 / 683

= 1

So, Greatest Common Divisor of 987, 131, 689, 683 is 1
