Given numbers are 830, 753, 442, 478

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 753 are 3 x 251

Prime factors of 442 are 2 x 13 x 17

Prime factors of 478 are 2 x 239

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

Given numbers are 830, 753, 442, 478

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

Apply this formula for all numbers.

Step1:

LCM(830, 753) = 624990

GCD(830, 753) = ( 830 x 753 ) / 624990

= 830 / 753

= 830

Step2:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 830, 753, 442, 478 is 1
