Given numbers are 420,242,181,862,330

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

The LCM of 420,242,181,862,330 is 3964519020.

Find LCM of 420,242,181,862,330 with Prime Factorization

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

2 x 3 x 5 x 11 x 14 x 1 x 181 x 431 x 11 = 3964519020

Therefore, the lowest common multiple of 420,242,181,862,330 is 3964519020.

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 242 x 181 x 862 x 330 = 5233165106400

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

242 : 1, 2, 11, 22, 121, 242

181 : 1, 181

862 : 1, 2, 431, 862

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,242,181,862,330, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

242:2x 11x 11

181:181

862:2x 431

330:2x 3x 5x 11

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

2x 2x 2x 3x 5x 11 = 1320

Therefore, the value for common factors is 1320.

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 = 5233165106400/(1x1320)

LCM = 5233165106400/1320

LCM = 3964519020

Thus, we can understand that the LCM of 420,242,181,862,330 is 3964519020.
