Given numbers are 770, 343, 855, 798

The list of prime factors of all numbers are

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 343 are 7 x 7 x 7

Prime factors of 855 are 3 x 3 x 5 x 19

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

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

Given numbers are 770, 343, 855, 798

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

Apply this formula for all numbers.

Step1:

LCM(770, 343) = 37730

GCD(770, 343) = ( 770 x 343 ) / 37730

= 770 / 343

= 770

Step2:

LCM(7, 855) = 5985

GCD(7, 855) = ( 7 x 855 ) / 5985

= 7 / 855

= 7

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 770, 343, 855, 798 is 1
