Given numbers are 822, 545, 779, 630

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 545 are 5 x 109

Prime factors of 779 are 19 x 41

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 822, 545, 779, 630

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

Apply this formula for all numbers.

Step1:

LCM(822, 545) = 447990

GCD(822, 545) = ( 822 x 545 ) / 447990

= 822 / 545

= 822

Step2:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 822, 545, 779, 630 is 1
