Given numbers are 780, 561, 470, 995

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 561 are 3 x 11 x 17

Prime factors of 470 are 2 x 5 x 47

Prime factors of 995 are 5 x 199

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

Given numbers are 780, 561, 470, 995

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

Apply this formula for all numbers.

Step1:

LCM(780, 561) = 145860

GCD(780, 561) = ( 780 x 561 ) / 145860

= 780 / 561

= 780

Step2:

LCM(3, 470) = 1410

GCD(3, 470) = ( 3 x 470 ) / 1410

= 3 / 470

= 3

Step3:

LCM(1, 995) = 995

GCD(1, 995) = ( 1 x 995 ) / 995

= 1 / 995

= 1

So, Greatest Common Divisor of 780, 561, 470, 995 is 1
