Given numbers are 163,663,172,724,985

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

The LCM of 163,663,172,724,985 is 3313938046380.

Find LCM of 163,663,172,724,985 with Prime Factorization

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

2 x 2 x 163 x 663 x 43 x 181 x 985 = 3313938046380

Therefore, the lowest common multiple of 163,663,172,724,985 is 3313938046380.

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 663 x 172 x 724 x 985 = 13255752185520

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

663 : 1, 3, 13, 17, 39, 51, 221, 663

172 : 1, 2, 4, 43, 86, 172

724 : 1, 2, 4, 181, 362, 724

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,663,172,724,985, is 1.

Now, the common factors can be found like this.

163:163

663:3x 13x 17

172:2x 2x 43

724:2x 2x 181

985:5x 197

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 13255752185520/(1x4)

LCM = 13255752185520/4

LCM = 3313938046380

Thus, we can understand that the LCM of 163,663,172,724,985 is 3313938046380.
