Given numbers are 557, 446, 400, 780

The list of prime factors of all numbers are

Prime factors of 557 are 557

Prime factors of 446 are 2 x 223

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

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

Given numbers are 557, 446, 400, 780

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

Apply this formula for all numbers.

Step1:

LCM(557, 446) = 248422

GCD(557, 446) = ( 557 x 446 ) / 248422

= 557 / 446

= 557

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 557, 446, 400, 780 is 1
