Given numbers are 822, 528, 803, 390

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 803 are 11 x 73

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 822, 528, 803, 390

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

Apply this formula for all numbers.

Step1:

LCM(822, 528) = 72336

GCD(822, 528) = ( 822 x 528 ) / 72336

= 822 / 528

= 822

Step2:

LCM(6, 803) = 4818

GCD(6, 803) = ( 6 x 803 ) / 4818

= 6 / 803

= 6

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 822, 528, 803, 390 is 1
