Given numbers are 830, 845, 40, 121

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 845 are 5 x 13 x 13

Prime factors of 40 are 2 x 2 x 2 x 5

Prime factors of 121 are 11 x 11

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

Given numbers are 830, 845, 40, 121

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

Apply this formula for all numbers.

Step1:

LCM(830, 845) = 140270

GCD(830, 845) = ( 830 x 845 ) / 140270

= 830 / 845

= 830

Step2:

LCM(5, 40) = 40

GCD(5, 40) = ( 5 x 40 ) / 40

= 5 / 40

= 5

Step3:

LCM(5, 121) = 605

GCD(5, 121) = ( 5 x 121 ) / 605

= 5 / 121

= 5

So, Greatest Common Divisor of 830, 845, 40, 121 is 1
