Given numbers are 170,221,878,998

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

The LCM of 170,221,878,998 is 484124810.

Find LCM of 170,221,878,998 with Prime Factorization

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

2 x 17 x 5 x 13 x 439 x 499 = 484124810

Therefore, the lowest common multiple of 170,221,878,998 is 484124810.

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.

170 x 221 x 878 x 998 = 32920487080

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.

170 : 1, 2, 5, 10, 17, 34, 85, 170

221 : 1, 13, 17, 221

878 : 1, 2, 439, 878

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,221,878,998, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

221:13x 17

878:2x 439

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.

2x 2x 17 = 68

Therefore, the value for common factors is 68.

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 = 32920487080/(1x68)

LCM = 32920487080/68

LCM = 484124810

Thus, we can understand that the LCM of 170,221,878,998 is 484124810.
