Given numbers are 578,221,454,194

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

The LCM of 578,221,454,194 is 165450766.

Find LCM of 578,221,454,194 with Prime Factorization

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

2 x 17 x 17 x 13 x 227 x 97 = 165450766

Therefore, the lowest common multiple of 578,221,454,194 is 165450766.

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.

578 x 221 x 454 x 194 = 11250652088

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.

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

221 : 1, 13, 17, 221

454 : 1, 2, 227, 454

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,221,454,194, is 1.

Now, the common factors can be found like this.

578:2x 17x 17

221:13x 17

454:2x 227

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 17 = 68

Therefore, the value for common factors is 68.

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 = 11250652088/(1x68)

LCM = 11250652088/68

LCM = 165450766

Thus, we can understand that the LCM of 578,221,454,194 is 165450766.
