Given numbers are 987, 646, 185, 981

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

Apply this formula for all numbers.

Step1:

LCM(987, 646) = 637602

GCD(987, 646) = ( 987 x 646 ) / 637602

= 987 / 646

= 987

Step2:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 987, 646, 185, 981 is 1
