Given numbers are 609,28,521

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

The LCM of 609,28,521 is 1269156.

Find LCM of 609,28,521 with Prime Factorization

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

7 x 87 x 4 x 521 = 1269156

Therefore, the lowest common multiple of 609,28,521 is 1269156.

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.

609 x 28 x 521 = 8884092

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

28 : 1, 2, 4, 7, 14, 28

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,28,521, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

28:2x 2x 7

521:521

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

7 = 7

Therefore, the value for common factors is 7.

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 = 8884092/(1x7)

LCM = 8884092/7

LCM = 1269156

Thus, we can understand that the LCM of 609,28,521 is 1269156.

Here are some samples of LCM of two or more Numbers calculations.
