Given numbers are 540,715,860,386

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

The LCM of 540,715,860,386 is 640848780.

Find LCM of 540,715,860,386 with Prime Factorization

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

2 x 2 x 5 x 27 x 143 x 43 x 193 = 640848780

Therefore, the lowest common multiple of 540,715,860,386 is 640848780.

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.

540 x 715 x 860 x 386 = 128169756000

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.

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

715 : 1, 5, 11, 13, 55, 65, 143, 715

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,715,860,386, is 1.

Now, the common factors can be found like this.

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

715:5x 11x 13

860:2x 2x 5x 43

386:2x 193

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 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 128169756000/(1x200)

LCM = 128169756000/200

LCM = 640848780

Thus, we can understand that the LCM of 540,715,860,386 is 640848780.
