Given numbers are 511,217,691

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

The LCM of 511,217,691 is 10946131.

Find LCM of 511,217,691 with Prime Factorization

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

7 x 73 x 31 x 691 = 10946131

Therefore, the lowest common multiple of 511,217,691 is 10946131.

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.

511 x 217 x 691 = 76622917

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.

511 : 1, 7, 73, 511

217 : 1, 7, 31, 217

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,217,691, is 1.

Now, the common factors can be found like this.

511:7x 73

217:7x 31

691:691

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 = 76622917/(1x7)

LCM = 76622917/7

LCM = 10946131

Thus, we can understand that the LCM of 511,217,691 is 10946131.

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

• LCM of 196, 885, 166
• LCM of 370, 646, 989
