Given numbers are 780, 780, 347, 853

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 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 347 are 347

Prime factors of 853 are 853

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

Given numbers are 780, 780, 347, 853

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

Apply this formula for all numbers.

Step1:

LCM(780, 780) = 780

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

= 780 / 780

= 780

Step2:

LCM(780, 347) = 270660

GCD(780, 347) = ( 780 x 347 ) / 270660

= 780 / 347

= 780

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 780, 780, 347, 853 is 1
