Given numbers are 663,743,247

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

The LCM of 663,743,247 is 9359571.

Find LCM of 663,743,247 with Prime Factorization

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

13 x 51 x 743 x 19 = 9359571

Therefore, the lowest common multiple of 663,743,247 is 9359571.

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.

663 x 743 x 247 = 121674423

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

743 : 1, 743

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,743,247, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

743:743

247:13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 121674423/(1x13)

LCM = 121674423/13

LCM = 9359571

Thus, we can understand that the LCM of 663,743,247 is 9359571.

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

• LCM of 824, 217, 186
• LCM of 562, 375, 707
