Given numbers are 817,393,722,286

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

The LCM of 817,393,722,286 is 1744754154.

Find LCM of 817,393,722,286 with Prime Factorization

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

2 x 19 x 43 x 393 x 19 x 143 = 1744754154

Therefore, the lowest common multiple of 817,393,722,286 is 1744754154.

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.

817 x 393 x 722 x 286 = 66300657852

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.

817 : 1, 19, 43, 817

393 : 1, 3, 131, 393

722 : 1, 2, 19, 38, 361, 722

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 817,393,722,286, is 1.

Now, the common factors can be found like this.

817:19x 43

393:3x 131

722:2x 19x 19

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 19 = 38

Therefore, the value for common factors is 38.

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 = 66300657852/(1x38)

LCM = 66300657852/38

LCM = 1744754154

Thus, we can understand that the LCM of 817,393,722,286 is 1744754154.
