Given numbers are 919,578,920,997

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

The LCM of 919,578,920,997 is 243610688840.

Find LCM of 919,578,920,997 with Prime Factorization

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

2 x 919 x 289 x 460 x 997 = 243610688840

Therefore, the lowest common multiple of 919,578,920,997 is 243610688840.

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.

919 x 578 x 920 x 997 = 487221377680

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.

919 : 1, 919

578 : 1, 2, 17, 34, 289, 578

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,578,920,997, is 1.

Now, the common factors can be found like this.

919:919

578:2x 17x 17

920:2x 2x 2x 5x 23

997:997

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 = 487221377680/(1x2)

LCM = 487221377680/2

LCM = 243610688840

Thus, we can understand that the LCM of 919,578,920,997 is 243610688840.
