The LCM of 309,618,684,779 is 2888532.

Find LCM of 309,618,684,779 with Prime Factorization


2 309, 618, 684, 779
3 309, 309, 342, 779
19 103, 103, 114, 779
103 103, 103, 6, 41
1, 1, 6, 41

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

2 x 3 x 19 x 103 x 1 x 1 x 6 x 41 = 2888532

Therefore, the lowest common multiple of 309,618,684,779 is 2888532.

LCM Formula to Find Lowest Common Multiple of 309,618,684,779

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.

309 x 618 x 684 x 779 = 101751428232

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.

309 : 1, 3, 103, 309

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

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,618,684,779, is 1.

Now, the common factors can be found like this.

309:3x 103

618:2x 3x 103

684:2x 2x 3x 3x 19

779:19x 41

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 19x 103 = 35226

Therefore, the value for common factors is 35226.

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 = 101751428232/(1x35226)

LCM = 101751428232/35226

LCM = 2888532

Thus, we can understand that the LCM of 309,618,684,779 is 2888532.
