Given numbers are 685,29,180

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

The LCM of 685,29,180 is 715140.

Find LCM of 685,29,180 with Prime Factorization

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

5 x 137 x 29 x 36 = 715140

Therefore, the lowest common multiple of 685,29,180 is 715140.

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.

685 x 29 x 180 = 3575700

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.

685 : 1, 5, 137, 685

29 : 1, 29

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,29,180, is 1.

Now, the common factors can be found like this.

685:5x 137

29:29

180:2x 2x 3x 3x 5

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

5 = 5

Therefore, the value for common factors is 5.

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 = 3575700/(1x5)

LCM = 3575700/5

LCM = 715140

Thus, we can understand that the LCM of 685,29,180 is 715140.

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

• LCM of 964, 24, 861
• LCM of 325, 94, 671
