Calculate the LCM of 724,888,442,380

Given numbers are 724,888,442,380

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

The LCM of 724,888,442,380 is 3374484360.

Find LCM of 724,888,442,380 with Prime Factorization


2 724, 888, 442, 380
2 362, 444, 221, 190
181, 222, 221, 95

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

2 x 2 x 181 x 222 x 221 x 95 = 3374484360

Therefore, the lowest common multiple of 724,888,442,380 is 3374484360.

LCM Formula to Find Lowest Common Multiple of 724,888,442,380

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.

724 x 888 x 442 x 380 = 107983499520

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.

724 : 1, 2, 4, 181, 362, 724

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

442 : 1, 2, 13, 17, 26, 34, 221, 442

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,888,442,380, is 2.

Now, the common factors can be found like this.

724:2x 2x 181

888:2x 2x 2x 3x 37

442:2x 13x 17

380:2x 2x 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.

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 107983499520/(2x16)

LCM = 107983499520/32

LCM = 3374484360

Thus, we can understand that the LCM of 724,888,442,380 is 3374484360.
