Given numbers are 291,448,921,394

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

The LCM of 291,448,921,394 is 7884526272.

Find LCM of 291,448,921,394 with Prime Factorization

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

2 x 3 x 97 x 224 x 307 x 197 = 7884526272

Therefore, the lowest common multiple of 291,448,921,394 is 7884526272.

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.

291 x 448 x 921 x 394 = 47307157632

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.

291 : 1, 3, 97, 291

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

921 : 1, 3, 307, 921

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,448,921,394, is 1.

Now, the common factors can be found like this.

291:3x 97

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

921:3x 307

394:2x 197

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 47307157632/(1x6)

LCM = 47307157632/6

LCM = 7884526272

Thus, we can understand that the LCM of 291,448,921,394 is 7884526272.
