The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 971 are 971

Prime factors of 148 are 2 x 2 x 37

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

Given numbers are 991, 840, 971, 148

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

Apply this formula for all numbers.

Step1:

LCM(991, 840) = 832440

GCD(991, 840) = ( 991 x 840 ) / 832440

= 991 / 840

= 991

Step2:

LCM(1, 971) = 971

GCD(1, 971) = ( 1 x 971 ) / 971

= 1 / 971

= 1

Step3:

LCM(1, 148) = 148

GCD(1, 148) = ( 1 x 148 ) / 148

= 1 / 148

= 1

So, Greatest Common Divisor of 991, 840, 971, 148 is 1
