Given numbers are 822, 421, 534, 747

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 421 are 421

Prime factors of 534 are 2 x 3 x 89

Prime factors of 747 are 3 x 3 x 83

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

Given numbers are 822, 421, 534, 747

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

Apply this formula for all numbers.

Step1:

LCM(822, 421) = 346062

GCD(822, 421) = ( 822 x 421 ) / 346062

= 822 / 421

= 822

Step2:

LCM(1, 534) = 534

GCD(1, 534) = ( 1 x 534 ) / 534

= 1 / 534

= 1

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 822, 421, 534, 747 is 1
