Given numbers are 321,991,392,898

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

The LCM of 321,991,392,898 is 55990080888.

Find LCM of 321,991,392,898 with Prime Factorization

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

2 x 321 x 991 x 196 x 449 = 55990080888

Therefore, the lowest common multiple of 321,991,392,898 is 55990080888.

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.

321 x 991 x 392 x 898 = 111980161776

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.

321 : 1, 3, 107, 321

991 : 1, 991

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,991,392,898, is 1.

Now, the common factors can be found like this.

321:3x 107

991:991

392:2x 2x 2x 7x 7

898:2x 449

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

2 = 2

Therefore, the value for common factors is 2.

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 = 111980161776/(1x2)

LCM = 111980161776/2

LCM = 55990080888

Thus, we can understand that the LCM of 321,991,392,898 is 55990080888.
