Given numbers are 870,646,998

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

The LCM of 870,646,998 is 140223990.

Find LCM of 870,646,998 with Prime Factorization

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

2 x 435 x 323 x 499 = 140223990

Therefore, the lowest common multiple of 870,646,998 is 140223990.

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.

870 x 646 x 998 = 560895960

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.

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

646 : 1, 2, 17, 19, 34, 38, 323, 646

998 : 1, 2, 499, 998

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,646,998, is 2.

Now, the common factors can be found like this.

870:2x 3x 5x 29

646:2x 17x 19

998:2x 499

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

2 = 2

Therefore, the value for common factors is 2.

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 = 560895960/(2x2)

LCM = 560895960/4

LCM = 140223990

Thus, we can understand that the LCM of 870,646,998 is 140223990.
