Given numbers are 782,557,286,290

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

The LCM of 782,557,286,290 is 9031626890.

Find LCM of 782,557,286,290 with Prime Factorization

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

2 x 391 x 557 x 143 x 145 = 9031626890

Therefore, the lowest common multiple of 782,557,286,290 is 9031626890.

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.

782 x 557 x 286 x 290 = 36126507560

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

557 : 1, 557

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

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,557,286,290, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

557:557

286:2x 11x 13

290:2x 5x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 36126507560/(1x4)

LCM = 36126507560/4

LCM = 9031626890

Thus, we can understand that the LCM of 782,557,286,290 is 9031626890.
