Given numbers are 996, 981, 992, 661

The list of prime factors of all numbers are

Prime factors of 996 are 2 x 2 x 3 x 83

Prime factors of 981 are 3 x 3 x 109

Prime factors of 992 are 2 x 2 x 2 x 2 x 2 x 31

Prime factors of 661 are 661

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

Given numbers are 996, 981, 992, 661

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

Apply this formula for all numbers.

Step1:

LCM(996, 981) = 325692

GCD(996, 981) = ( 996 x 981 ) / 325692

= 996 / 981

= 996

Step2:

LCM(3, 992) = 2976

GCD(3, 992) = ( 3 x 992 ) / 2976

= 3 / 992

= 3

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 996, 981, 992, 661 is 1
