Given numbers are 420,540,888,659,286

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

The LCM of 420,540,888,659,286 is 26359973640.

Find LCM of 420,540,888,659,286 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 9 x 74 x 659 x 143 = 26359973640

Therefore, the lowest common multiple of 420,540,888,659,286 is 26359973640.

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.

420 x 540 x 888 x 659 x 286 = 37958362041600

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

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

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

659 : 1, 659

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,540,888,659,286, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

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

888:2x 2x 2x 3x 37

659:659

286:2x 11x 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 2x 2x 2x 3x 3x 5 = 1440

Therefore, the value for common factors is 1440.

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 = 37958362041600/(1x1440)

LCM = 37958362041600/1440

LCM = 26359973640

Thus, we can understand that the LCM of 420,540,888,659,286 is 26359973640.
