Given numbers are 991, 778, 495, 432

The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 778 are 2 x 389

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 991, 778, 495, 432

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

Apply this formula for all numbers.

Step1:

LCM(991, 778) = 770998

GCD(991, 778) = ( 991 x 778 ) / 770998

= 991 / 778

= 991

Step2:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

Step3:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

So, Greatest Common Divisor of 991, 778, 495, 432 is 1
