Given numbers are 221,381,187,402

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

The LCM of 221,381,187,402 is 124112274.

Find LCM of 221,381,187,402 with Prime Factorization

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

3 x 17 x 13 x 127 x 11 x 134 = 124112274

Therefore, the lowest common multiple of 221,381,187,402 is 124112274.

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.

221 x 381 x 187 x 402 = 6329725974

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.

221 : 1, 13, 17, 221

381 : 1, 3, 127, 381

187 : 1, 11, 17, 187

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,381,187,402, is 1.

Now, the common factors can be found like this.

221:13x 17

381:3x 127

187:11x 17

402:2x 3x 67

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

3x 17 = 51

Therefore, the value for common factors is 51.

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 = 6329725974/(1x51)

LCM = 6329725974/51

LCM = 124112274

Thus, we can understand that the LCM of 221,381,187,402 is 124112274.
