Given numbers are 780, 470, 437, 847

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 470 are 2 x 5 x 47

Prime factors of 437 are 19 x 23

Prime factors of 847 are 7 x 11 x 11

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

Given numbers are 780, 470, 437, 847

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

Apply this formula for all numbers.

Step1:

LCM(780, 470) = 36660

GCD(780, 470) = ( 780 x 470 ) / 36660

= 780 / 470

= 780

Step2:

LCM(10, 437) = 4370

GCD(10, 437) = ( 10 x 437 ) / 4370

= 10 / 437

= 10

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 780, 470, 437, 847 is 1
