Given numbers are 771, 432, 836, 390

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

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

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 771, 432, 836, 390

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

Apply this formula for all numbers.

Step1:

LCM(771, 432) = 111024

GCD(771, 432) = ( 771 x 432 ) / 111024

= 771 / 432

= 771

Step2:

LCM(3, 836) = 2508

GCD(3, 836) = ( 3 x 836 ) / 2508

= 3 / 836

= 3

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 771, 432, 836, 390 is 1
