Given numbers are 521,221,190,817

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

The LCM of 521,221,190,817 is 940701970.

Find LCM of 521,221,190,817 with Prime Factorization

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

19 x 521 x 221 x 10 x 43 = 940701970

Therefore, the lowest common multiple of 521,221,190,817 is 940701970.

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.

521 x 221 x 190 x 817 = 17873337430

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.

521 : 1, 521

221 : 1, 13, 17, 221

190 : 1, 2, 5, 10, 19, 38, 95, 190

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,221,190,817, is 1.

Now, the common factors can be found like this.

521:521

221:13x 17

190:2x 5x 19

817:19x 43

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

19 = 19

Therefore, the value for common factors is 19.

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 = 17873337430/(1x19)

LCM = 17873337430/19

LCM = 940701970

Thus, we can understand that the LCM of 521,221,190,817 is 940701970.
