Given numbers are 420,417,283

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

The LCM of 420,417,283 is 16521540.

Find LCM of 420,417,283 with Prime Factorization

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

3 x 140 x 139 x 283 = 16521540

Therefore, the lowest common multiple of 420,417,283 is 16521540.

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.

420 x 417 x 283 = 49564620

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

417 : 1, 3, 139, 417

283 : 1, 283

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,417,283, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

417:3x 139

283:283

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

3 = 3

Therefore, the value for common factors is 3.

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 = 49564620/(1x3)

LCM = 49564620/3

LCM = 16521540

Thus, we can understand that the LCM of 420,417,283 is 16521540.

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

• LCM of 632, 105, 880
