Given numbers are 419,442,994,678

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

The LCM of 419,442,994,678 is 31202714634.

Find LCM of 419,442,994,678 with Prime Factorization

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

2 x 419 x 221 x 497 x 339 = 31202714634

Therefore, the lowest common multiple of 419,442,994,678 is 31202714634.

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.

419 x 442 x 994 x 678 = 124810858536

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.

419 : 1, 419

442 : 1, 2, 13, 17, 26, 34, 221, 442

994 : 1, 2, 7, 14, 71, 142, 497, 994

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,442,994,678, is 1.

Now, the common factors can be found like this.

419:419

442:2x 13x 17

994:2x 7x 71

678:2x 3x 113

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 124810858536/(1x4)

LCM = 124810858536/4

LCM = 31202714634

Thus, we can understand that the LCM of 419,442,994,678 is 31202714634.
