Calculate the LCM of 299,789,138,618

Given numbers are 299,789,138,618

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

The LCM of 299,789,138,618 is 48597666.

Find LCM of 299,789,138,618 with Prime Factorization


2 299, 789, 138, 618
3 299, 789, 69, 309
23 299, 263, 23, 103
13, 263, 1, 103

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

2 x 3 x 23 x 13 x 263 x 1 x 103 = 48597666

Therefore, the lowest common multiple of 299,789,138,618 is 48597666.

LCM Formula to Find Lowest Common Multiple of 299,789,138,618

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 789 x 138 x 618 = 20119433724

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

789 : 1, 3, 263, 789

138 : 1, 2, 3, 6, 23, 46, 69, 138

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,789,138,618, is 1.

Now, the common factors can be found like this.

299:13x 23

789:3x 263

138:2x 3x 23

618:2x 3x 103

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

2x 3x 3x 23 = 414

Therefore, the value for common factors is 414.

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 = 20119433724/(1x414)

LCM = 20119433724/414

LCM = 48597666

Thus, we can understand that the LCM of 299,789,138,618 is 48597666.
