Given numbers are 609,613,721

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

The LCM of 609,613,721 is 38451651.

Find LCM of 609,613,721 with Prime Factorization

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

7 x 87 x 613 x 103 = 38451651

Therefore, the lowest common multiple of 609,613,721 is 38451651.

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 613 x 721 = 269161557

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

613 : 1, 613

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,613,721, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

613:613

721:7x 103

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 = 269161557/(1x7)

LCM = 269161557/7

LCM = 38451651

Thus, we can understand that the LCM of 609,613,721 is 38451651.

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

• LCM of 974, 498, 572
• LCM of 745, 698, 893
