Given numbers are 921,749,321

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

The LCM of 921,749,321 is 689829.

Find LCM of 921,749,321 with Prime Factorization

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

3 x 107 x 307 x 7 x 1 = 689829

Therefore, the lowest common multiple of 921,749,321 is 689829.

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.

921 x 749 x 321 = 221435109

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.

921 : 1, 3, 307, 921

749 : 1, 7, 107, 749

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,749,321, is 1.

Now, the common factors can be found like this.

921:3x 307

749:7x 107

321:3x 107

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

3x 107 = 321

Therefore, the value for common factors is 321.

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 = 221435109/(1x321)

LCM = 221435109/321

LCM = 689829

Thus, we can understand that the LCM of 921,749,321 is 689829.

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

• LCM of 317, 923, 448
• LCM of 382, 295, 966
