Given numbers are 631,368,874,890

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

The LCM of 631,368,874,890 is 1963318640.

Find LCM of 631,368,874,890 with Prime Factorization

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

2 x 23 x 631 x 8 x 19 x 445 = 1963318640

Therefore, the lowest common multiple of 631,368,874,890 is 1963318640.

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.

631 x 368 x 874 x 890 = 180625314880

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.

631 : 1, 631

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

874 : 1, 2, 19, 23, 38, 46, 437, 874

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,368,874,890, is 1.

Now, the common factors can be found like this.

631:631

368:2x 2x 2x 2x 23

874:2x 19x 23

890:2x 5x 89

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 23 = 92

Therefore, the value for common factors is 92.

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 = 180625314880/(1x92)

LCM = 180625314880/92

LCM = 1963318640

Thus, we can understand that the LCM of 631,368,874,890 is 1963318640.
