Given numbers are 780, 805, 228, 103

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 805 are 5 x 7 x 23

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 103 are 103

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

Given numbers are 780, 805, 228, 103

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

Apply this formula for all numbers.

Step1:

LCM(780, 805) = 125580

GCD(780, 805) = ( 780 x 805 ) / 125580

= 780 / 805

= 780

Step2:

LCM(5, 228) = 1140

GCD(5, 228) = ( 5 x 228 ) / 1140

= 5 / 228

= 5

Step3:

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

= 1 / 103

= 1

So, Greatest Common Divisor of 780, 805, 228, 103 is 1
