Calculate the LCM of 469,920,897,638,289

Given numbers are 469,920,897,638,289

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

The LCM of 469,920,897,638,289 is 1551364334520.

Find LCM of 469,920,897,638,289 with Prime Factorization


2 469, 920, 897, 638, 289
23 469, 460, 897, 319, 289
469, 20, 39, 319, 289

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

2 x 23 x 469 x 20 x 39 x 319 x 289 = 1551364334520

Therefore, the lowest common multiple of 469,920,897,638,289 is 1551364334520.

LCM Formula to Find Lowest Common Multiple of 469,920,897,638,289

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.

469 x 920 x 897 x 638 x 289 = 71362759387920

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.

469 : 1, 7, 67, 469

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

897 : 1, 3, 13, 23, 39, 69, 299, 897

638 : 1, 2, 11, 22, 29, 58, 319, 638

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,920,897,638,289, is 1.

Now, the common factors can be found like this.

469:7x 67

920:2x 2x 2x 5x 23

897:3x 13x 23

638:2x 11x 29

289:17x 17

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 71362759387920/(1x46)

LCM = 71362759387920/46

LCM = 1551364334520

Thus, we can understand that the LCM of 469,920,897,638,289 is 1551364334520.
