Given numbers are 391,638,433,402

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

The LCM of 391,638,433,402 is 21711078114.

Find LCM of 391,638,433,402 with Prime Factorization

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

2 x 391 x 319 x 433 x 201 = 21711078114

Therefore, the lowest common multiple of 391,638,433,402 is 21711078114.

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 638 x 433 x 402 = 43422156228

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

433 : 1, 433

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,638,433,402, is 1.

Now, the common factors can be found like this.

391:17x 23

638:2x 11x 29

433:433

402:2x 3x 67

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

2 = 2

Therefore, the value for common factors is 2.

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 = 43422156228/(1x2)

LCM = 43422156228/2

LCM = 21711078114

Thus, we can understand that the LCM of 391,638,433,402 is 21711078114.
