Given numbers are 770, 208, 775, 517

The list of prime factors of all numbers are

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

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 775 are 5 x 5 x 31

Prime factors of 517 are 11 x 47

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

Given numbers are 770, 208, 775, 517

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

Apply this formula for all numbers.

Step1:

LCM(770, 208) = 80080

GCD(770, 208) = ( 770 x 208 ) / 80080

= 770 / 208

= 770

Step2:

LCM(2, 775) = 1550

GCD(2, 775) = ( 2 x 775 ) / 1550

= 2 / 775

= 2

Step3:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

So, Greatest Common Divisor of 770, 208, 775, 517 is 1
