The LCM of 612,289,225,217 is 56441700.

Find LCM of 612,289,225,217 with Prime Factorization


3 612, 289, 225, 217
3 204, 289, 75, 217
17 68, 289, 25, 217
4, 17, 25, 217

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

3 x 3 x 17 x 4 x 17 x 25 x 217 = 56441700

Therefore, the lowest common multiple of 612,289,225,217 is 56441700.

LCM Formula to Find Lowest Common Multiple of 612,289,225,217

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.

612 x 289 x 225 x 217 = 8635580100

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.

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

289 : 1, 17, 289

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,289,225,217, is 1.

Now, the common factors can be found like this.

612:2x 2x 3x 3x 17

289:17x 17

225:3x 3x 5x 5

217:7x 31

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

3x 3x 17 = 153

Therefore, the value for common factors is 153.

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 = 8635580100/(1x153)

LCM = 8635580100/153

LCM = 56441700

Thus, we can understand that the LCM of 612,289,225,217 is 56441700.
