Given numbers are 425,164,656,540,721

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

The LCM of 425,164,656,540,721 is 5427399600.

Find LCM of 425,164,656,540,721 with Prime Factorization

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

2 x 2 x 5 x 41 x 85 x 1 x 4 x 27 x 721 = 5427399600

Therefore, the lowest common multiple of 425,164,656,540,721 is 5427399600.

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.

425 x 164 x 656 x 540 x 721 = 17801870688000

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.

425 : 1, 5, 17, 25, 85, 425

164 : 1, 2, 4, 41, 82, 164

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,164,656,540,721, is 1.

Now, the common factors can be found like this.

425:5x 5x 17

164:2x 2x 41

656:2x 2x 2x 2x 41

540:2x 2x 3x 3x 3x 5

721:7x 103

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 2x 2x 5x 41 = 3280

Therefore, the value for common factors is 3280.

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 = 17801870688000/(1x3280)

LCM = 17801870688000/3280

LCM = 5427399600

Thus, we can understand that the LCM of 425,164,656,540,721 is 5427399600.
