Find LCM of 842,864,135,515 with Prime Factorization


2 842, 864, 135, 515
3 421, 432, 135, 515
3 421, 144, 45, 515
3 421, 48, 15, 515
5 421, 16, 5, 515
421, 16, 1, 103

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

2 x 3 x 3 x 3 x 5 x 421 x 16 x 1 x 103 = 187328160

Therefore, the lowest common multiple of 842,864,135,515 is 187328160.

LCM Formula to Find Lowest Common Multiple of 842,864,135,515

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.

842 x 864 x 135 x 515 = 50578603200

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.

842 : 1, 2, 421, 842

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

135 : 1, 3, 5, 9, 15, 27, 45, 135

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,864,135,515, is 1.

Now, the common factors can be found like this.

842:2x 421

864:2x 2x 2x 2x 2x 3x 3x 3

135:3x 3x 3x 5

515:5x 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 3x 5 = 270

Therefore, the value for common factors is 270.

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 = 50578603200/(1x270)

LCM = 50578603200/270

LCM = 187328160

Thus, we can understand that the LCM of 842,864,135,515 is 187328160.
