Given numbers are 747, 426, 670, 728

The list of prime factors of all numbers are

Prime factors of 747 are 3 x 3 x 83

Prime factors of 426 are 2 x 3 x 71

Prime factors of 670 are 2 x 5 x 67

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 747, 426, 670, 728

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

Apply this formula for all numbers.

Step1:

LCM(747, 426) = 106074

GCD(747, 426) = ( 747 x 426 ) / 106074

= 747 / 426

= 747

Step2:

LCM(3, 670) = 2010

GCD(3, 670) = ( 3 x 670 ) / 2010

= 3 / 670

= 3

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 747, 426, 670, 728 is 1
