Given numbers are 417,423,821,376

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

The LCM of 417,423,821,376 is 386178696.

Find LCM of 417,423,821,376 with Prime Factorization

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

3 x 47 x 139 x 3 x 821 x 8 = 386178696

Therefore, the lowest common multiple of 417,423,821,376 is 386178696.

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.

417 x 423 x 821 x 376 = 54451196136

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.

417 : 1, 3, 139, 417

423 : 1, 3, 9, 47, 141, 423

821 : 1, 821

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,423,821,376, is 1.

Now, the common factors can be found like this.

417:3x 139

423:3x 3x 47

821:821

376:2x 2x 2x 47

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

3x 47 = 141

Therefore, the value for common factors is 141.

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 = 54451196136/(1x141)

LCM = 54451196136/141

LCM = 386178696

Thus, we can understand that the LCM of 417,423,821,376 is 386178696.
