Given numbers are 674,440,242,660

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

The LCM of 674,440,242,660 is 4893240.

Find LCM of 674,440,242,660 with Prime Factorization

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

2 x 2 x 5 x 11 x 337 x 2 x 11 x 3 = 4893240

Therefore, the lowest common multiple of 674,440,242,660 is 4893240.

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.

674 x 440 x 242 x 660 = 47366563200

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.

674 : 1, 2, 337, 674

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

242 : 1, 2, 11, 22, 121, 242

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,440,242,660, is 2.

Now, the common factors can be found like this.

674:2x 337

440:2x 2x 2x 5x 11

242:2x 11x 11

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 11x 11 = 4840

Therefore, the value for common factors is 4840.

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 = 47366563200/(2x4840)

LCM = 47366563200/9680

LCM = 4893240

Thus, we can understand that the LCM of 674,440,242,660 is 4893240.
