Given numbers are 858,249,757,990

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

The LCM of 858,249,757,990 is 808634970.

Find LCM of 858,249,757,990 with Prime Factorization

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

2 x 3 x 11 x 13 x 83 x 757 x 15 = 808634970

Therefore, the lowest common multiple of 858,249,757,990 is 808634970.

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.

858 x 249 x 757 x 990 = 160109724060

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

249 : 1, 3, 83, 249

757 : 1, 757

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,249,757,990, is 1.

Now, the common factors can be found like this.

858:2x 3x 11x 13

249:3x 83

757:757

990:2x 3x 3x 5x 11

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

2x 3x 3x 11 = 198

Therefore, the value for common factors is 198.

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 = 160109724060/(1x198)

LCM = 160109724060/198

LCM = 808634970

Thus, we can understand that the LCM of 858,249,757,990 is 808634970.
