Given numbers are 217, 702, 447, 830

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 447 are 3 x 149

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 217, 702, 447, 830

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

Apply this formula for all numbers.

Step1:

LCM(217, 702) = 152334

GCD(217, 702) = ( 217 x 702 ) / 152334

= 217 / 702

= 217

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 217, 702, 447, 830 is 1
