Given numbers are 478, 546, 858, 747

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 858 are 2 x 3 x 11 x 13

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 478, 546, 858, 747

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

Apply this formula for all numbers.

Step1:

LCM(478, 546) = 130494

GCD(478, 546) = ( 478 x 546 ) / 130494

= 478 / 546

= 478

Step2:

LCM(2, 858) = 858

GCD(2, 858) = ( 2 x 858 ) / 858

= 2 / 858

= 2

Step3:

LCM(2, 747) = 1494

GCD(2, 747) = ( 2 x 747 ) / 1494

= 2 / 747

= 2

So, Greatest Common Divisor of 478, 546, 858, 747 is 1
