Given numbers are 402,415,669,921,429

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

The LCM of 402,415,669,921,429 is 1633252854090.

Find LCM of 402,415,669,921,429 with Prime Factorization

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

3 x 134 x 415 x 223 x 307 x 143 = 1633252854090

Therefore, the lowest common multiple of 402,415,669,921,429 is 1633252854090.

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.

402 x 415 x 669 x 921 x 429 = 44097827060430

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.

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

415 : 1, 5, 83, 415

669 : 1, 3, 223, 669

921 : 1, 3, 307, 921

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,415,669,921,429, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

415:5x 83

669:3x 223

921:3x 307

429:3x 11x 13

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 3 = 27

Therefore, the value for common factors is 27.

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 = 44097827060430/(1x27)

LCM = 44097827060430/27

LCM = 1633252854090

Thus, we can understand that the LCM of 402,415,669,921,429 is 1633252854090.
