Given numbers are 787,247,646

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

The LCM of 787,247,646 is 6609226.

Find LCM of 787,247,646 with Prime Factorization

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

19 x 787 x 13 x 34 = 6609226

Therefore, the lowest common multiple of 787,247,646 is 6609226.

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.

787 x 247 x 646 = 125575294

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.

787 : 1, 787

247 : 1, 13, 19, 247

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,247,646, is 1.

Now, the common factors can be found like this.

787:787

247:13x 19

646:2x 17x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 125575294/(1x19)

LCM = 125575294/19

LCM = 6609226

Thus, we can understand that the LCM of 787,247,646 is 6609226.

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

• LCM of 816, 150, 147
• LCM of 953, 864, 609
