Given numbers are 670,740,515,391,390

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

The LCM of 670,740,515,391,390 is 77872678260.

Find LCM of 670,740,515,391,390 with Prime Factorization

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

2 x 5 x 67 x 74 x 103 x 391 x 39 = 77872678260

Therefore, the lowest common multiple of 670,740,515,391,390 is 77872678260.

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.

670 x 740 x 515 x 391 x 390 = 38936339130000

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

515 : 1, 5, 103, 515

391 : 1, 17, 23, 391

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,740,515,391,390, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

740:2x 2x 5x 37

515:5x 103

391:17x 23

390:2x 3x 5x 13

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 5x 5x 5 = 500

Therefore, the value for common factors is 500.

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 = 38936339130000/(1x500)

LCM = 38936339130000/500

LCM = 77872678260

Thus, we can understand that the LCM of 670,740,515,391,390 is 77872678260.
