Given numbers are 981, 678, 641, 976

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

Apply this formula for all numbers.

Step1:

LCM(981, 678) = 221706

GCD(981, 678) = ( 981 x 678 ) / 221706

= 981 / 678

= 981

Step2:

LCM(3, 641) = 1923

GCD(3, 641) = ( 3 x 641 ) / 1923

= 3 / 641

= 3

Step3:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

So, Greatest Common Divisor of 981, 678, 641, 976 is 1
