Given numbers are 981, 640, 180, 293

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 293 are 293

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 981, 640, 180, 293

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

Apply this formula for all numbers.

Step1:

LCM(981, 640) = 627840

GCD(981, 640) = ( 981 x 640 ) / 627840

= 981 / 640

= 981

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 293) = 293

GCD(1, 293) = ( 1 x 293 ) / 293

= 1 / 293

= 1

So, Greatest Common Divisor of 981, 640, 180, 293 is 1
