Given numbers are 678,406,377,194

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

The LCM of 678,406,377,194 is 173556474.

Find LCM of 678,406,377,194 with Prime Factorization

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

2 x 29 x 339 x 7 x 13 x 97 = 173556474

Therefore, the lowest common multiple of 678,406,377,194 is 173556474.

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.

678 x 406 x 377 x 194 = 20132550984

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.

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

406 : 1, 2, 7, 14, 29, 58, 203, 406

377 : 1, 13, 29, 377

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,406,377,194, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

406:2x 7x 29

377:13x 29

194:2x 97

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 29 = 116

Therefore, the value for common factors is 116.

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 = 20132550984/(1x116)

LCM = 20132550984/116

LCM = 173556474

Thus, we can understand that the LCM of 678,406,377,194 is 173556474.
