Given numbers are 178,421,910,356

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

The LCM of 178,421,910,356 is 68193580.

Find LCM of 178,421,910,356 with Prime Factorization

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

2 x 89 x 1 x 421 x 455 x 2 = 68193580

Therefore, the lowest common multiple of 178,421,910,356 is 68193580.

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.

178 x 421 x 910 x 356 = 24276914480

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.

178 : 1, 2, 89, 178

421 : 1, 421

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

356 : 1, 2, 4, 89, 178, 356

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,421,910,356, is 1.

Now, the common factors can be found like this.

178:2x 89

421:421

910:2x 5x 7x 13

356:2x 2x 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 89 = 356

Therefore, the value for common factors is 356.

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 = 24276914480/(1x356)

LCM = 24276914480/356

LCM = 68193580

Thus, we can understand that the LCM of 178,421,910,356 is 68193580.
