Given numbers are 7191,5123

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 7191,5123 is 783819.

Find LCM of 7191,5123 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

47 x 153 x 109 = 783819

Therefore, the lowest common multiple of 7191,5123 is 783819.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

7191 x 5123 = 36839493

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

7191 : 1, 3, 9, 17, 47, 51, 141, 153, 423, 799, 2397, 7191

5123 : 1, 47, 109, 5123

47 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7191,5123, is 47.

Now, the common factors can be found like this.

7191:3x 3x 17x 47

5123:47x 109

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 36839493/(47x1)

LCM = 36839493/47

LCM = 783819

Thus, we can understand that the LCM of 7191,5123 is 783819.
