Given numbers are 161,751,630,920,575

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

The LCM of 161,751,630,920,575 is 217639800.

Find LCM of 161,751,630,920,575 with Prime Factorization

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

2 x 5 x 7 x 23 x 1 x 751 x 9 x 4 x 5 = 217639800

Therefore, the lowest common multiple of 161,751,630,920,575 is 217639800.

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.

161 x 751 x 630 x 920 x 575 = 40296008970000

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.

161 : 1, 7, 23, 161

751 : 1, 751

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

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 161,751,630,920,575, is 1.

Now, the common factors can be found like this.

161:7x 23

751:751

630:2x 3x 3x 5x 7

920:2x 2x 2x 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 5x 5x 7x 23x 23 = 185150

Therefore, the value for common factors is 185150.

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 = 40296008970000/(1x185150)

LCM = 40296008970000/185150

LCM = 217639800

Thus, we can understand that the LCM of 161,751,630,920,575 is 217639800.
