Given numbers are 777, 505, 707, 390

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 505 are 5 x 101

Prime factors of 707 are 7 x 101

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

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

Given numbers are 777, 505, 707, 390

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

Apply this formula for all numbers.

Step1:

LCM(777, 505) = 392385

GCD(777, 505) = ( 777 x 505 ) / 392385

= 777 / 505

= 777

Step2:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 777, 505, 707, 390 is 1
