Given numbers are 949, 415, 115, 840

The list of prime factors of all numbers are

Prime factors of 949 are 13 x 73

Prime factors of 415 are 5 x 83

Prime factors of 115 are 5 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 949, 415, 115, 840

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

Apply this formula for all numbers.

Step1:

LCM(949, 415) = 393835

GCD(949, 415) = ( 949 x 415 ) / 393835

= 949 / 415

= 949

Step2:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 949, 415, 115, 840 is 1
