Given numbers are 423, 642, 820, 675

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 642 are 2 x 3 x 107

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

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

Given numbers are 423, 642, 820, 675

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

Apply this formula for all numbers.

Step1:

LCM(423, 642) = 90522

GCD(423, 642) = ( 423 x 642 ) / 90522

= 423 / 642

= 423

Step2:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

Step3:

LCM(1, 675) = 675

GCD(1, 675) = ( 1 x 675 ) / 675

= 1 / 675

= 1

So, Greatest Common Divisor of 423, 642, 820, 675 is 1
