Given numbers are 822, 815, 638, 411

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 815 are 5 x 163

Prime factors of 638 are 2 x 11 x 29

Prime factors of 411 are 3 x 137

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

Given numbers are 822, 815, 638, 411

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

Apply this formula for all numbers.

Step1:

LCM(822, 815) = 669930

GCD(822, 815) = ( 822 x 815 ) / 669930

= 822 / 815

= 822

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 822, 815, 638, 411 is 1
