Given numbers are 490,989,204,721

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

The LCM of 490,989,204,721 is 5091312660.

Find LCM of 490,989,204,721 with Prime Factorization

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

2 x 7 x 35 x 989 x 102 x 103 = 5091312660

Therefore, the lowest common multiple of 490,989,204,721 is 5091312660.

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.

490 x 989 x 204 x 721 = 71278377240

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.

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

989 : 1, 23, 43, 989

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,989,204,721, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

989:23x 43

204:2x 2x 3x 17

721:7x 103

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 71278377240/(1x14)

LCM = 71278377240/14

LCM = 5091312660

Thus, we can understand that the LCM of 490,989,204,721 is 5091312660.

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

• LCM of 374, 655, 532, 800
