Given numbers are 981, 473, 487, 660

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 473 are 11 x 43

Prime factors of 487 are 487

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 981, 473, 487, 660

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

Apply this formula for all numbers.

Step1:

LCM(981, 473) = 464013

GCD(981, 473) = ( 981 x 473 ) / 464013

= 981 / 473

= 981

Step2:

LCM(1, 487) = 487

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

= 1 / 487

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 981, 473, 487, 660 is 1
