Given numbers are 220,647,283,455,440

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

The LCM of 220,647,283,455,440 is 7331364040.

Find LCM of 220,647,283,455,440 with Prime Factorization

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

2 x 2 x 5 x 11 x 1 x 647 x 283 x 91 x 2 = 7331364040

Therefore, the lowest common multiple of 220,647,283,455,440 is 7331364040.

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.

220 x 647 x 283 x 455 x 440 = 8064500444000

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.

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

647 : 1, 647

283 : 1, 283

455 : 1, 5, 7, 13, 35, 65, 91, 455

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,647,283,455,440, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

647:647

283:283

455:5x 7x 13

440:2x 2x 2x 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 5x 5x 11 = 1100

Therefore, the value for common factors is 1100.

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 = 8064500444000/(1x1100)

LCM = 8064500444000/1100

LCM = 7331364040

Thus, we can understand that the LCM of 220,647,283,455,440 is 7331364040.
