The LCM of 844,915,690,575 is 88809900.

Find LCM of 844,915,690,575 with Prime Factorization


2 844, 915, 690, 575
3 422, 915, 345, 575
5 422, 305, 115, 575
23 422, 61, 23, 115
422, 61, 1, 5

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

2 x 3 x 5 x 23 x 422 x 61 x 1 x 5 = 88809900

Therefore, the lowest common multiple of 844,915,690,575 is 88809900.

LCM Formula to Find Lowest Common Multiple of 844,915,690,575

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.

844 x 915 x 690 x 575 = 306394155000

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.

844 : 1, 2, 4, 211, 422, 844

915 : 1, 3, 5, 15, 61, 183, 305, 915

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

575 : 1, 5, 23, 25, 115, 575

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,915,690,575, is 1.

Now, the common factors can be found like this.

844:2x 2x 211

915:3x 5x 61

690:2x 3x 5x 23

575:5x 5x 23

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 5x 5x 23 = 3450

Therefore, the value for common factors is 3450.

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 = 306394155000/(1x3450)

LCM = 306394155000/3450

LCM = 88809900

Thus, we can understand that the LCM of 844,915,690,575 is 88809900.
