Given numbers are 215, 830, 703, 120

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 830 are 2 x 5 x 83

Prime factors of 703 are 19 x 37

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 215, 830, 703, 120

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

Apply this formula for all numbers.

Step1:

LCM(215, 830) = 35690

GCD(215, 830) = ( 215 x 830 ) / 35690

= 215 / 830

= 215

Step2:

LCM(5, 703) = 3515

GCD(5, 703) = ( 5 x 703 ) / 3515

= 5 / 703

= 5

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 215, 830, 703, 120 is 1
