Given numbers are 391,697,671

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

The LCM of 391,697,671 is 10756801.

Find LCM of 391,697,671 with Prime Factorization

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

17 x 23 x 41 x 671 = 10756801

Therefore, the lowest common multiple of 391,697,671 is 10756801.

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.

391 x 697 x 671 = 182865617

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.

391 : 1, 17, 23, 391

697 : 1, 17, 41, 697

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,697,671, is 1.

Now, the common factors can be found like this.

391:17x 23

697:17x 41

671:11x 61

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

17 = 17

Therefore, the value for common factors is 17.

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 = 182865617/(1x17)

LCM = 182865617/17

LCM = 10756801

Thus, we can understand that the LCM of 391,697,671 is 10756801.

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

• LCM of 497, 622, 513
• LCM of 958, 945, 299
