Given numbers are 170,390,888,502,721

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

The LCM of 170,390,888,502,721 is 177575984040.

Find LCM of 170,390,888,502,721 with Prime Factorization

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

2 x 3 x 5 x 17 x 13 x 148 x 251 x 721 = 177575984040

Therefore, the lowest common multiple of 170,390,888,502,721 is 177575984040.

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 390 x 888 x 502 x 721 = 21309118084800

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

502 : 1, 2, 251, 502

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,390,888,502,721, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

390:2x 3x 5x 13

888:2x 2x 2x 3x 37

502:2x 251

721:7x 103

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 2x 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 21309118084800/(1x120)

LCM = 21309118084800/120

LCM = 177575984040

Thus, we can understand that the LCM of 170,390,888,502,721 is 177575984040.
