Given numbers are 446, 780, 194, 653

The list of prime factors of all numbers are

Prime factors of 446 are 2 x 223

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

Prime factors of 194 are 2 x 97

Prime factors of 653 are 653

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

Given numbers are 446, 780, 194, 653

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

Apply this formula for all numbers.

Step1:

LCM(446, 780) = 173940

GCD(446, 780) = ( 446 x 780 ) / 173940

= 446 / 780

= 446

Step2:

LCM(2, 194) = 194

GCD(2, 194) = ( 2 x 194 ) / 194

= 2 / 194

= 2

Step3:

LCM(2, 653) = 1306

GCD(2, 653) = ( 2 x 653 ) / 1306

= 2 / 653

= 2

So, Greatest Common Divisor of 446, 780, 194, 653 is 1
