Given numbers are 454,345,578,19

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

The LCM of 454,345,578,19 is 860055330.

Find LCM of 454,345,578,19 with Prime Factorization

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

2 x 227 x 345 x 289 x 19 = 860055330

Therefore, the lowest common multiple of 454,345,578,19 is 860055330.

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.

454 x 345 x 578 x 19 = 1720110660

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.

454 : 1, 2, 227, 454

345 : 1, 3, 5, 15, 23, 69, 115, 345

578 : 1, 2, 17, 34, 289, 578

19 : 1, 19

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,345,578,19, is 1.

Now, the common factors can be found like this.

454:2x 227

345:3x 5x 23

578:2x 17x 17

19:19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 1720110660/(1x2)

LCM = 1720110660/2

LCM = 860055330

Thus, we can understand that the LCM of 454,345,578,19 is 860055330.
