Given numbers are 530, 308, 822, 783

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 822 are 2 x 3 x 137

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 530, 308, 822, 783

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

Apply this formula for all numbers.

Step1:

LCM(530, 308) = 81620

GCD(530, 308) = ( 530 x 308 ) / 81620

= 530 / 308

= 530

Step2:

LCM(2, 822) = 822

GCD(2, 822) = ( 2 x 822 ) / 822

= 2 / 822

= 2

Step3:

LCM(2, 783) = 1566

GCD(2, 783) = ( 2 x 783 ) / 1566

= 2 / 783

= 2

So, Greatest Common Divisor of 530, 308, 822, 783 is 1
