Given numbers are 490,663,872

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

The LCM of 490,663,872 is 141643320.

Find LCM of 490,663,872 with Prime Factorization

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

2 x 245 x 663 x 436 = 141643320

Therefore, the lowest common multiple of 490,663,872 is 141643320.

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 663 x 872 = 283286640

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

663 : 1, 3, 13, 17, 39, 51, 221, 663

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,663,872, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

663:3x 13x 17

872:2x 2x 2x 109

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 = 283286640/(1x2)

LCM = 283286640/2

LCM = 141643320

Thus, we can understand that the LCM of 490,663,872 is 141643320.
