Given numbers are 772,18,309

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

The LCM of 772,18,309 is 715644.

Find LCM of 772,18,309 with Prime Factorization

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

2 x 3 x 386 x 3 x 103 = 715644

Therefore, the lowest common multiple of 772,18,309 is 715644.

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.

772 x 18 x 309 = 4293864

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.

772 : 1, 2, 4, 193, 386, 772

18 : 1, 2, 3, 6, 9, 18

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,18,309, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

18:2x 3x 3

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 4293864/(1x6)

LCM = 4293864/6

LCM = 715644

Thus, we can understand that the LCM of 772,18,309 is 715644.

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

• LCM of 736, 73, 862
• LCM of 118, 49, 128
