Given numbers are 770, 170, 412, 749

The list of prime factors of all numbers are

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

Prime factors of 170 are 2 x 5 x 17

Prime factors of 412 are 2 x 2 x 103

Prime factors of 749 are 7 x 107

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

Given numbers are 770, 170, 412, 749

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

Apply this formula for all numbers.

Step1:

LCM(770, 170) = 13090

GCD(770, 170) = ( 770 x 170 ) / 13090

= 770 / 170

= 770

Step2:

LCM(10, 412) = 2060

GCD(10, 412) = ( 10 x 412 ) / 2060

= 10 / 412

= 10

Step3:

LCM(2, 749) = 1498

GCD(2, 749) = ( 2 x 749 ) / 1498

= 2 / 749

= 2

So, Greatest Common Divisor of 770, 170, 412, 749 is 1
