Given numbers are 448,668,909,217

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

The LCM of 448,668,909,217 is 2108240064.

Find LCM of 448,668,909,217 with Prime Factorization

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

2 x 2 x 7 x 16 x 167 x 909 x 31 = 2108240064

Therefore, the lowest common multiple of 448,668,909,217 is 2108240064.

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.

448 x 668 x 909 x 217 = 59030721792

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.

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

668 : 1, 2, 4, 167, 334, 668

909 : 1, 3, 9, 101, 303, 909

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 448,668,909,217, is 1.

Now, the common factors can be found like this.

448:2x 2x 2x 2x 2x 2x 7

668:2x 2x 167

909:3x 3x 101

217:7x 31

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 7 = 28

Therefore, the value for common factors is 28.

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 = 59030721792/(1x28)

LCM = 59030721792/28

LCM = 2108240064

Thus, we can understand that the LCM of 448,668,909,217 is 2108240064.
