Calculate the LCM of 287,249,589,855

Given numbers are 287,249,589,855

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

The LCM of 287,249,589,855 is 631375605.

Find LCM of 287,249,589,855 with Prime Factorization


3 287, 249, 589, 855
19 287, 83, 589, 285
287, 83, 31, 15

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

3 x 19 x 287 x 83 x 31 x 15 = 631375605

Therefore, the lowest common multiple of 287,249,589,855 is 631375605.

LCM Formula to Find Lowest Common Multiple of 287,249,589,855

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.

287 x 249 x 589 x 855 = 35988409485

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.

287 : 1, 7, 41, 287

249 : 1, 3, 83, 249

589 : 1, 19, 31, 589

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,249,589,855, is 1.

Now, the common factors can be found like this.

287:7x 41

249:3x 83

589:19x 31

855:3x 3x 5x 19

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 35988409485/(1x57)

LCM = 35988409485/57

LCM = 631375605

Thus, we can understand that the LCM of 287,249,589,855 is 631375605.
