Given numbers are 381,845,762,997

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

The LCM of 381,845,762,997 is 641958330.

Find LCM of 381,845,762,997 with Prime Factorization

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

3 x 127 x 1 x 845 x 2 x 997 = 641958330

Therefore, the lowest common multiple of 381,845,762,997 is 641958330.

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.

381 x 845 x 762 x 997 = 244586123730

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.

381 : 1, 3, 127, 381

845 : 1, 5, 13, 65, 169, 845

762 : 1, 2, 3, 6, 127, 254, 381, 762

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,845,762,997, is 1.

Now, the common factors can be found like this.

381:3x 127

845:5x 13x 13

762:2x 3x 127

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.

3x 127 = 381

Therefore, the value for common factors is 381.

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 = 244586123730/(1x381)

LCM = 244586123730/381

LCM = 641958330

Thus, we can understand that the LCM of 381,845,762,997 is 641958330.
