Given numbers are 991, 805, 408, 742

The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 805 are 5 x 7 x 23

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 742 are 2 x 7 x 53

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

Given numbers are 991, 805, 408, 742

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

Apply this formula for all numbers.

Step1:

LCM(991, 805) = 797755

GCD(991, 805) = ( 991 x 805 ) / 797755

= 991 / 805

= 991

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

So, Greatest Common Divisor of 991, 805, 408, 742 is 1
