Given numbers are 3157,9919

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

The LCM of 3157,9919 is 4473469.

Find LCM of 3157,9919 with Prime Factorization

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

7 x 451 x 1417 = 4473469

Therefore, the lowest common multiple of 3157,9919 is 4473469.

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.

3157 x 9919 = 31314283

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.

3157 : 1, 7, 11, 41, 77, 287, 451, 3157

9919 : 1, 7, 13, 91, 109, 763, 1417, 9919

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3157,9919, is 7.

Now, the common factors can be found like this.

3157:7x 11x 41

9919:7x 13x 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 = 31314283/(7x1)

LCM = 31314283/7

LCM = 4473469

Thus, we can understand that the LCM of 3157,9919 is 4473469.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 6642, 3569
