Given numbers are 780, 471, 554, 779

The list of prime factors of all numbers are

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

Prime factors of 471 are 3 x 157

Prime factors of 554 are 2 x 277

Prime factors of 779 are 19 x 41

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

Given numbers are 780, 471, 554, 779

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

Apply this formula for all numbers.

Step1:

LCM(780, 471) = 122460

GCD(780, 471) = ( 780 x 471 ) / 122460

= 780 / 471

= 780

Step2:

LCM(3, 554) = 1662

GCD(3, 554) = ( 3 x 554 ) / 1662

= 3 / 554

= 3

Step3:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

So, Greatest Common Divisor of 780, 471, 554, 779 is 1
