Given numbers are 669,63,343

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

The LCM of 669,63,343 is 688401.

Find LCM of 669,63,343 with Prime Factorization

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

3 x 7 x 223 x 3 x 49 = 688401

Therefore, the lowest common multiple of 669,63,343 is 688401.

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.

669 x 63 x 343 = 14456421

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.

669 : 1, 3, 223, 669

63 : 1, 3, 7, 9, 21, 63

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,63,343, is 1.

Now, the common factors can be found like this.

669:3x 223

63:3x 3x 7

343:7x 7x 7

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 14456421/(1x21)

LCM = 14456421/21

LCM = 688401

Thus, we can understand that the LCM of 669,63,343 is 688401.

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

• LCM of 335, 55, 673
• LCM of 416, 95, 951
