Given numbers are 470,421,396,454

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

The LCM of 470,421,396,454 is 8893465020.

Find LCM of 470,421,396,454 with Prime Factorization

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

2 x 235 x 421 x 198 x 227 = 8893465020

Therefore, the lowest common multiple of 470,421,396,454 is 8893465020.

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.

470 x 421 x 396 x 454 = 35573860080

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.

470 : 1, 2, 5, 10, 47, 94, 235, 470

421 : 1, 421

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,421,396,454, is 1.

Now, the common factors can be found like this.

470:2x 5x 47

421:421

396:2x 2x 3x 3x 11

454:2x 227

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 35573860080/(1x4)

LCM = 35573860080/4

LCM = 8893465020

Thus, we can understand that the LCM of 470,421,396,454 is 8893465020.
