Given numbers are 90,289,242

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

The LCM of 90,289,242 is 3147210.

Find LCM of 90,289,242 with Prime Factorization

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

2 x 45 x 289 x 121 = 3147210

Therefore, the lowest common multiple of 90,289,242 is 3147210.

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 289 x 242 = 6294420

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

289 : 1, 17, 289

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 90,289,242, is 1.

Now, the common factors can be found like this.

90:2x 3x 3x 5

289:17x 17

242:2x 11x 11

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 = 6294420/(1x2)

LCM = 6294420/2

LCM = 3147210

Thus, we can understand that the LCM of 90,289,242 is 3147210.

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

• LCM of 49, 873, 443
• LCM of 88, 709, 610
