Given numbers are 819, 620, 522, 705

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 705 are 3 x 5 x 47

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

Given numbers are 819, 620, 522, 705

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

Apply this formula for all numbers.

Step1:

LCM(819, 620) = 507780

GCD(819, 620) = ( 819 x 620 ) / 507780

= 819 / 620

= 819

Step2:

LCM(1, 522) = 522

GCD(1, 522) = ( 1 x 522 ) / 522

= 1 / 522

= 1

Step3:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

So, Greatest Common Divisor of 819, 620, 522, 705 is 1
