Calculate the LCM of 258,723,448,391

Given numbers are 258,723,448,391

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

The LCM of 258,723,448,391 is 5445797952.

Find LCM of 258,723,448,391 with Prime Factorization


2 258, 723, 448, 391
3 129, 723, 224, 391
43, 241, 224, 391

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

2 x 3 x 43 x 241 x 224 x 391 = 5445797952

Therefore, the lowest common multiple of 258,723,448,391 is 5445797952.

LCM Formula to Find Lowest Common Multiple of 258,723,448,391

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.

258 x 723 x 448 x 391 = 32674787712

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.

258 : 1, 2, 3, 6, 43, 86, 129, 258

723 : 1, 3, 241, 723

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,723,448,391, is 1.

Now, the common factors can be found like this.

258:2x 3x 43

723:3x 241

448:2x 2x 2x 2x 2x 2x 7

391:17x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 32674787712/(1x6)

LCM = 32674787712/6

LCM = 5445797952

Thus, we can understand that the LCM of 258,723,448,391 is 5445797952.
