Find GCD of 47, 11, 13, 28 using Prime Factorization

Given numbers are 47, 11, 13, 28

The list of prime factors of all numbers are

Prime factors of 47 are 47

Prime factors of 11 are 11

Prime factors of 13 are 13

Prime factors of 28 are 2 x 2 x 7

Steps to Calculate GCD of 47, 11, 13, 28 using LCM Formula

Given numbers are 47, 11, 13, 28

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

Apply this formula for all numbers.

Step1:

LCM(47, 11) = 517

GCD(47, 11) = ( 47 x 11 ) / 517

= 47 / 11

= 47


Step2:

LCM(1, 13) = 13

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

= 1 / 13

= 1


Step3:

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

= 1 / 28

= 1


So, Greatest Common Divisor of 47, 11, 13, 28 is 1
