Given numbers are 390,635,770,440

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

The LCM of 390,635,770,440 is 15255240.

Find LCM of 390,635,770,440 with Prime Factorization

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

2 x 5 x 11 x 39 x 127 x 7 x 4 = 15255240

Therefore, the lowest common multiple of 390,635,770,440 is 15255240.

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.

390 x 635 x 770 x 440 = 83903820000

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.

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

635 : 1, 5, 127, 635

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,635,770,440, is 5.

Now, the common factors can be found like this.

390:2x 3x 5x 13

635:5x 127

770:2x 5x 7x 11

440:2x 2x 2x 5x 11

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 11 = 1100

Therefore, the value for common factors is 1100.

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 = 83903820000/(5x1100)

LCM = 83903820000/5500

LCM = 15255240

Thus, we can understand that the LCM of 390,635,770,440 is 15255240.
