Given numbers are 291,429,639,213

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

The LCM of 291,429,639,213 is 8863569.

Find LCM of 291,429,639,213 with Prime Factorization

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

3 x 71 x 97 x 143 x 3 x 1 = 8863569

Therefore, the lowest common multiple of 291,429,639,213 is 8863569.

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.

291 x 429 x 639 x 213 = 16991461773

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.

291 : 1, 3, 97, 291

429 : 1, 3, 11, 13, 33, 39, 143, 429

639 : 1, 3, 9, 71, 213, 639

213 : 1, 3, 71, 213

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,429,639,213, is 3.

Now, the common factors can be found like this.

291:3x 97

429:3x 11x 13

639:3x 3x 71

213:3x 71

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

3x 3x 71 = 639

Therefore, the value for common factors is 639.

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 = 16991461773/(3x639)

LCM = 16991461773/1917

LCM = 8863569

Thus, we can understand that the LCM of 291,429,639,213 is 8863569.
