Given numbers are 755, 390, 770, 419

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 390 are 2 x 3 x 5 x 13

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

Prime factors of 419 are 419

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

Given numbers are 755, 390, 770, 419

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

Apply this formula for all numbers.

Step1:

LCM(755, 390) = 58890

GCD(755, 390) = ( 755 x 390 ) / 58890

= 755 / 390

= 755

Step2:

LCM(5, 770) = 770

GCD(5, 770) = ( 5 x 770 ) / 770

= 5 / 770

= 5

Step3:

LCM(5, 419) = 2095

GCD(5, 419) = ( 5 x 419 ) / 2095

= 5 / 419

= 5

So, Greatest Common Divisor of 755, 390, 770, 419 is 1
