Given numbers are 221,697,170,439

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

The LCM of 221,697,170,439 is 39777790.

Find LCM of 221,697,170,439 with Prime Factorization

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

17 x 13 x 41 x 10 x 439 = 39777790

Therefore, the lowest common multiple of 221,697,170,439 is 39777790.

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.

221 x 697 x 170 x 439 = 11495781310

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.

221 : 1, 13, 17, 221

697 : 1, 17, 41, 697

170 : 1, 2, 5, 10, 17, 34, 85, 170

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,697,170,439, is 1.

Now, the common factors can be found like this.

221:13x 17

697:17x 41

170:2x 5x 17

439:439

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 11495781310/(1x289)

LCM = 11495781310/289

LCM = 39777790

Thus, we can understand that the LCM of 221,697,170,439 is 39777790.
