Given numbers are 248,970,355,921

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

The LCM of 248,970,355,921 is 7865229480.

Find LCM of 248,970,355,921 with Prime Factorization

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

2 x 5 x 124 x 97 x 71 x 921 = 7865229480

Therefore, the lowest common multiple of 248,970,355,921 is 7865229480.

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.

248 x 970 x 355 x 921 = 78652294800

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.

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

970 : 1, 2, 5, 10, 97, 194, 485, 970

355 : 1, 5, 71, 355

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,970,355,921, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

970:2x 5x 97

355:5x 71

921:3x 307

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 78652294800/(1x10)

LCM = 78652294800/10

LCM = 7865229480

Thus, we can understand that the LCM of 248,970,355,921 is 7865229480.
