Given numbers are 991, 660, 504, 392

The list of prime factors of all numbers are

Prime factors of 991 are 991

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

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 991, 660, 504, 392

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

Apply this formula for all numbers.

Step1:

LCM(991, 660) = 654060

GCD(991, 660) = ( 991 x 660 ) / 654060

= 991 / 660

= 991

Step2:

LCM(1, 504) = 504

GCD(1, 504) = ( 1 x 504 ) / 504

= 1 / 504

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 991, 660, 504, 392 is 1
