Given numbers are 728,278,287,820,566

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

The LCM of 728,278,287,820,566 is 5870653880.

Find LCM of 728,278,287,820,566 with Prime Factorization

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

2 x 2 x 7 x 41 x 26 x 139 x 1 x 5 x 283 = 5870653880

Therefore, the lowest common multiple of 728,278,287,820,566 is 5870653880.

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.

728 x 278 x 287 x 820 x 566 = 26958042616960

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

278 : 1, 2, 139, 278

287 : 1, 7, 41, 287

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

566 : 1, 2, 283, 566

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,278,287,820,566, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

278:2x 139

287:7x 41

820:2x 2x 5x 41

566:2x 283

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 7x 41 = 4592

Therefore, the value for common factors is 4592.

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 = 26958042616960/(1x4592)

LCM = 26958042616960/4592

LCM = 5870653880

Thus, we can understand that the LCM of 728,278,287,820,566 is 5870653880.
