Given numbers are 446, 175, 780, 393

The list of prime factors of all numbers are

Prime factors of 446 are 2 x 223

Prime factors of 175 are 5 x 5 x 7

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 393 are 3 x 131

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

Given numbers are 446, 175, 780, 393

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

Apply this formula for all numbers.

Step1:

LCM(446, 175) = 78050

GCD(446, 175) = ( 446 x 175 ) / 78050

= 446 / 175

= 446

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 446, 175, 780, 393 is 1
