Given numbers are 355,440,274,660

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

The LCM of 355,440,274,660 is 12839640.

Find LCM of 355,440,274,660 with Prime Factorization

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

2 x 2 x 5 x 11 x 71 x 2 x 137 x 3 = 12839640

Therefore, the lowest common multiple of 355,440,274,660 is 12839640.

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.

355 x 440 x 274 x 660 = 28247208000

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.

355 : 1, 5, 71, 355

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

274 : 1, 2, 137, 274

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,440,274,660, is 1.

Now, the common factors can be found like this.

355:5x 71

440:2x 2x 2x 5x 11

274:2x 137

660:2x 2x 3x 5x 11

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

2x 2x 2x 5x 5x 11 = 2200

Therefore, the value for common factors is 2200.

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 = 28247208000/(1x2200)

LCM = 28247208000/2200

LCM = 12839640

Thus, we can understand that the LCM of 355,440,274,660 is 12839640.
