Given numbers are 840, 775, 798, 386

The list of prime factors of all numbers are

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

Prime factors of 775 are 5 x 5 x 31

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 386 are 2 x 193

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

Given numbers are 840, 775, 798, 386

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

Apply this formula for all numbers.

Step1:

LCM(840, 775) = 130200

GCD(840, 775) = ( 840 x 775 ) / 130200

= 840 / 775

= 840

Step2:

LCM(5, 798) = 3990

GCD(5, 798) = ( 5 x 798 ) / 3990

= 5 / 798

= 5

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 840, 775, 798, 386 is 1
