Given numbers are 127,660,391,423,402

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

The LCM of 127,660,391,423,402 is 309612388140.

Find LCM of 127,660,391,423,402 with Prime Factorization

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

2 x 3 x 127 x 110 x 391 x 141 x 67 = 309612388140

Therefore, the lowest common multiple of 127,660,391,423,402 is 309612388140.

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.

127 x 660 x 391 x 423 x 402 = 5573022986520

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.

127 : 1, 127

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

391 : 1, 17, 23, 391

423 : 1, 3, 9, 47, 141, 423

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 127,660,391,423,402, is 1.

Now, the common factors can be found like this.

127:127

660:2x 2x 3x 5x 11

391:17x 23

423:3x 3x 47

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.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 5573022986520/(1x18)

LCM = 5573022986520/18

LCM = 309612388140

Thus, we can understand that the LCM of 127,660,391,423,402 is 309612388140.
