Given numbers are 460,912,257,721

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

The LCM of 460,912,257,721 is 19433949360.

Find LCM of 460,912,257,721 with Prime Factorization

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

2 x 2 x 115 x 228 x 257 x 721 = 19433949360

Therefore, the lowest common multiple of 460,912,257,721 is 19433949360.

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.

460 x 912 x 257 x 721 = 77735797440

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.

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

257 : 1, 257

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,912,257,721, is 1.

Now, the common factors can be found like this.

460:2x 2x 5x 23

912:2x 2x 2x 2x 3x 19

257:257

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 2 = 4

Therefore, the value for common factors is 4.

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 = 77735797440/(1x4)

LCM = 77735797440/4

LCM = 19433949360

Thus, we can understand that the LCM of 460,912,257,721 is 19433949360.
