Given numbers are 107,305,390,398

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

The LCM of 107,305,390,398 is 506560470.

Find LCM of 107,305,390,398 with Prime Factorization

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

2 x 5 x 107 x 61 x 39 x 199 = 506560470

Therefore, the lowest common multiple of 107,305,390,398 is 506560470.

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.

107 x 305 x 390 x 398 = 5065604700

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.

107 : 1, 107

305 : 1, 5, 61, 305

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,305,390,398, is 1.

Now, the common factors can be found like this.

107:107

305:5x 61

390:2x 3x 5x 13

398:2x 199

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 5065604700/(1x10)

LCM = 5065604700/10

LCM = 506560470

Thus, we can understand that the LCM of 107,305,390,398 is 506560470.
