Given numbers are 163,728,721,195,491

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

The LCM of 163,728,721,195,491 is 90017917080.

Find LCM of 163,728,721,195,491 with Prime Factorization

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

7 x 13 x 163 x 8 x 103 x 15 x 491 = 90017917080

Therefore, the lowest common multiple of 163,728,721,195,491 is 90017917080.

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.

163 x 728 x 721 x 195 x 491 = 8191630454280

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.

163 : 1, 163

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

721 : 1, 7, 103, 721

195 : 1, 3, 5, 13, 15, 39, 65, 195

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,728,721,195,491, is 1.

Now, the common factors can be found like this.

163:163

728:2x 2x 2x 7x 13

721:7x 103

195:3x 5x 13

491:491

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

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 8191630454280/(1x91)

LCM = 8191630454280/91

LCM = 90017917080

Thus, we can understand that the LCM of 163,728,721,195,491 is 90017917080.
