Given numbers are 447, 427, 253, 780

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 427 are 7 x 61

Prime factors of 253 are 11 x 23

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 447, 427, 253, 780

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

Apply this formula for all numbers.

Step1:

LCM(447, 427) = 190869

GCD(447, 427) = ( 447 x 427 ) / 190869

= 447 / 427

= 447

Step2:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 447, 427, 253, 780 is 1
