Given numbers are 424, 646, 193, 780

The list of prime factors of all numbers are

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 646 are 2 x 17 x 19

Prime factors of 193 are 193

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 424, 646, 193, 780

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

Apply this formula for all numbers.

Step1:

LCM(424, 646) = 136952

GCD(424, 646) = ( 424 x 646 ) / 136952

= 424 / 646

= 424

Step2:

LCM(2, 193) = 386

GCD(2, 193) = ( 2 x 193 ) / 386

= 2 / 193

= 2

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 424, 646, 193, 780 is 1
