Find GCD of 61, 22, 71, 45 using Prime Factorization

Given numbers are 61, 22, 71, 45

The list of prime factors of all numbers are

Prime factors of 61 are 61

Prime factors of 22 are 2 x 11

Prime factors of 71 are 71

Prime factors of 45 are 3 x 3 x 5

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

Steps to Calculate GCD of 61, 22, 71, 45 using LCM Formula

Given numbers are 61, 22, 71, 45

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

Apply this formula for all numbers.

Step1:

LCM(61, 22) = 1342

GCD(61, 22) = ( 61 x 22 ) / 1342

= 61 / 22

= 61


Step2:

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

= 1 / 71

= 1


Step3:

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

= 1 / 45

= 1


So, Greatest Common Divisor of 61, 22, 71, 45 is 1
