The LCM of 170,230,784,317 is 485872240.

Find LCM of 170,230,784,317 with Prime Factorization


2 170, 230, 784, 317
5 85, 115, 392, 317
17, 23, 392, 317

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

2 x 5 x 17 x 23 x 392 x 317 = 485872240

Therefore, the lowest common multiple of 170,230,784,317 is 485872240.

LCM Formula to Find Lowest Common Multiple of 170,230,784,317

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.

170 x 230 x 784 x 317 = 9717444800

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.

170 : 1, 2, 5, 10, 17, 34, 85, 170

230 : 1, 2, 5, 10, 23, 46, 115, 230

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

317 : 1, 317

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,230,784,317, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

230:2x 5x 23

784:2x 2x 2x 2x 7x 7

317:317

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 5 = 20

Therefore, the value for common factors is 20.

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 = 9717444800/(1x20)

LCM = 9717444800/20

LCM = 485872240

Thus, we can understand that the LCM of 170,230,784,317 is 485872240.
