Given numbers are 90,22,85,454

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

The LCM of 90,22,85,454 is 3820410.

Find LCM of 90,22,85,454 with Prime Factorization

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

2 x 5 x 9 x 11 x 17 x 227 = 3820410

Therefore, the lowest common multiple of 90,22,85,454 is 3820410.

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.

90 x 22 x 85 x 454 = 76408200

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.

90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

22 : 1, 2, 11, 22

85 : 1, 5, 17, 85

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 90,22,85,454, is 1.

Now, the common factors can be found like this.

90:2x 3x 3x 5

22:2x 11

85:5x 17

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 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 76408200/(1x20)

LCM = 76408200/20

LCM = 3820410

Thus, we can understand that the LCM of 90,22,85,454 is 3820410.

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