Given numbers are 931,18,722

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

The LCM of 931,18,722 is 318402.

Find LCM of 931,18,722 with Prime Factorization

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

2 x 19 x 49 x 9 x 19 = 318402

Therefore, the lowest common multiple of 931,18,722 is 318402.

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.

931 x 18 x 722 = 12099276

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.

931 : 1, 7, 19, 49, 133, 931

18 : 1, 2, 3, 6, 9, 18

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,18,722, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

18:2x 3x 3

722:2x 19x 19

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 12099276/(1x38)

LCM = 12099276/38

LCM = 318402

Thus, we can understand that the LCM of 931,18,722 is 318402.

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

• LCM of 122, 65, 450
• LCM of 787, 78, 341
