Given numbers are 354,221,557,273

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

The LCM of 354,221,557,273 is 305034366.

Find LCM of 354,221,557,273 with Prime Factorization

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

3 x 13 x 118 x 17 x 557 x 7 = 305034366

Therefore, the lowest common multiple of 354,221,557,273 is 305034366.

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.

354 x 221 x 557 x 273 = 11896340274

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.

354 : 1, 2, 3, 6, 59, 118, 177, 354

221 : 1, 13, 17, 221

557 : 1, 557

273 : 1, 3, 7, 13, 21, 39, 91, 273

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,221,557,273, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

221:13x 17

557:557

273:3x 7x 13

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 11896340274/(1x39)

LCM = 11896340274/39

LCM = 305034366

Thus, we can understand that the LCM of 354,221,557,273 is 305034366.
