Given numbers are 822, 647, 520, 603

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 647 are 647

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 603 are 3 x 3 x 67

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

Given numbers are 822, 647, 520, 603

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

Apply this formula for all numbers.

Step1:

LCM(822, 647) = 531834

GCD(822, 647) = ( 822 x 647 ) / 531834

= 822 / 647

= 822

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 822, 647, 520, 603 is 1
