GCD of numbers is the greatest common divisor

So, the GCD (49, 65, 56, 13) = 1.

Given numbers are 49, 65, 56, 13

The list of prime factors of all numbers are

Prime factors of 49 are 7 x 7

Prime factors of 65 are 5 x 13

Prime factors of 56 are 2 x 2 x 2 x 7

Prime factors of 13 are 13

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

Given numbers are 49, 65, 56, 13

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

Apply this formula for all numbers.

Step1:

LCM(49, 65) = 3185

GCD(49, 65) = ( 49 x 65 ) / 3185

= 49 / 65

= 49

Step2:

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

= 1 / 56

= 1

Step3:

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

= 1 / 13

= 1

So, Greatest Common Divisor of 49, 65, 56, 13 is 1
