Given numbers are 830, 705, 39, 252

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 705 are 3 x 5 x 47

Prime factors of 39 are 3 x 13

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

Given numbers are 830, 705, 39, 252

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

Apply this formula for all numbers.

Step1:

LCM(830, 705) = 117030

GCD(830, 705) = ( 830 x 705 ) / 117030

= 830 / 705

= 830

Step2:

LCM(5, 39) = 195

GCD(5, 39) = ( 5 x 39 ) / 195

= 5 / 39

= 5

Step3:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

So, Greatest Common Divisor of 830, 705, 39, 252 is 1
