Given numbers are 521,830,521,186

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

The LCM of 521,830,521,186 is 40215990.

Find LCM of 521,830,521,186 with Prime Factorization

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

2 x 521 x 1 x 415 x 1 x 93 = 40215990

Therefore, the lowest common multiple of 521,830,521,186 is 40215990.

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 830 x 521 x 186 = 41905061580

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

830 : 1, 2, 5, 10, 83, 166, 415, 830

521 : 1, 521

186 : 1, 2, 3, 6, 31, 62, 93, 186

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,830,521,186, is 1.

Now, the common factors can be found like this.

521:521

830:2x 5x 83

521:521

186:2x 3x 31

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

2x 521 = 1042

Therefore, the value for common factors is 1042.

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 = 41905061580/(1x1042)

LCM = 41905061580/1042

LCM = 40215990

Thus, we can understand that the LCM of 521,830,521,186 is 40215990.
