Given numbers are 340, 770, 254, 857

The list of prime factors of all numbers are

Prime factors of 340 are 2 x 2 x 5 x 17

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

Prime factors of 254 are 2 x 127

Prime factors of 857 are 857

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

Given numbers are 340, 770, 254, 857

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

Apply this formula for all numbers.

Step1:

LCM(340, 770) = 26180

GCD(340, 770) = ( 340 x 770 ) / 26180

= 340 / 770

= 340

Step2:

LCM(10, 254) = 1270

GCD(10, 254) = ( 10 x 254 ) / 1270

= 10 / 254

= 10

Step3:

LCM(2, 857) = 1714

GCD(2, 857) = ( 2 x 857 ) / 1714

= 2 / 857

= 2

So, Greatest Common Divisor of 340, 770, 254, 857 is 1
