Given numbers are 86,17,97,17,221

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

The LCM of 86,17,97,17,221 is 1843582.

Find LCM of 86,17,97,17,221 with Prime Factorization

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

17 x 86 x 1 x 97 x 1 x 13 = 1843582

Therefore, the lowest common multiple of 86,17,97,17,221 is 1843582.

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.

86 x 17 x 97 x 17 x 221 = 532795198

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.

86 : 1, 2, 43, 86

17 : 1, 17

97 : 1, 97

17 : 1, 17

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 86,17,97,17,221, is 1.

Now, the common factors can be found like this.

86:2x 43

17:17

97:97

17:17

221:13x 17

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 = 532795198/(1x289)

LCM = 532795198/289

LCM = 1843582

Thus, we can understand that the LCM of 86,17,97,17,221 is 1843582.
