Given numbers are 578,221,403,668,195

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

The LCM of 578,221,403,668,195 is 1166999340.

Find LCM of 578,221,403,668,195 with Prime Factorization

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

2 x 13 x 17 x 1 x 17 x 31 x 334 x 15 = 1166999340

Therefore, the lowest common multiple of 578,221,403,668,195 is 1166999340.

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.

578 x 221 x 403 x 668 x 195 = 6705578207640

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.

578 : 1, 2, 17, 34, 289, 578

221 : 1, 13, 17, 221

403 : 1, 13, 31, 403

668 : 1, 2, 4, 167, 334, 668

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,221,403,668,195, is 1.

Now, the common factors can be found like this.

578:2x 17x 17

221:13x 17

403:13x 31

668:2x 2x 167

195:3x 5x 13

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

2x 13x 13x 17 = 5746

Therefore, the value for common factors is 5746.

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 = 6705578207640/(1x5746)

LCM = 6705578207640/5746

LCM = 1166999340

Thus, we can understand that the LCM of 578,221,403,668,195 is 1166999340.
