Given numbers are 721,247,309

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

The LCM of 721,247,309 is 534261.

Find LCM of 721,247,309 with Prime Factorization

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

103 x 7 x 247 x 3 = 534261

Therefore, the lowest common multiple of 721,247,309 is 534261.

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.

721 x 247 x 309 = 55028883

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.

721 : 1, 7, 103, 721

247 : 1, 13, 19, 247

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,247,309, is 1.

Now, the common factors can be found like this.

721:7x 103

247:13x 19

309:3x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 55028883/(1x103)

LCM = 55028883/103

LCM = 534261

Thus, we can understand that the LCM of 721,247,309 is 534261.

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

• LCM of 496, 433, 534
• LCM of 307, 377, 493
