Given numbers are 221,439,248,672

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

The LCM of 221,439,248,672 is 2021099808.

Find LCM of 221,439,248,672 with Prime Factorization

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

2 x 2 x 2 x 221 x 439 x 31 x 84 = 2021099808

Therefore, the lowest common multiple of 221,439,248,672 is 2021099808.

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 439 x 248 x 672 = 16168798464

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

439 : 1, 439

248 : 1, 2, 4, 8, 31, 62, 124, 248

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,439,248,672, is 1.

Now, the common factors can be found like this.

221:13x 17

439:439

248:2x 2x 2x 31

672:2x 2x 2x 2x 2x 3x 7

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 2 = 8

Therefore, the value for common factors is 8.

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 = 16168798464/(1x8)

LCM = 16168798464/8

LCM = 2021099808

Thus, we can understand that the LCM of 221,439,248,672 is 2021099808.
