Calculate the LCM of 299,738,286,642

Given numbers are 299,738,286,642

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

The LCM of 299,738,286,642 is 259719174.

Find LCM of 299,738,286,642 with Prime Factorization


2 299, 738, 286, 642
3 299, 369, 143, 321
13 299, 123, 143, 107
23, 123, 11, 107

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

2 x 3 x 13 x 23 x 123 x 11 x 107 = 259719174

Therefore, the lowest common multiple of 299,738,286,642 is 259719174.

LCM Formula to Find Lowest Common Multiple of 299,738,286,642

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.

299 x 738 x 286 x 642 = 40516191144

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.

299 : 1, 13, 23, 299

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

286 : 1, 2, 11, 13, 22, 26, 143, 286

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,738,286,642, is 1.

Now, the common factors can be found like this.

299:13x 23

738:2x 3x 3x 41

286:2x 11x 13

642:2x 3x 107

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 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 40516191144/(1x156)

LCM = 40516191144/156

LCM = 259719174

Thus, we can understand that the LCM of 299,738,286,642 is 259719174.
