Given numbers are 685,42,494

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

The LCM of 685,42,494 is 7106190.

Find LCM of 685,42,494 with Prime Factorization

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

2 x 685 x 21 x 247 = 7106190

Therefore, the lowest common multiple of 685,42,494 is 7106190.

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 42 x 494 = 14212380

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

42 : 1, 2, 3, 6, 7, 14, 21, 42

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,42,494, is 1.

Now, the common factors can be found like this.

685:5x 137

42:2x 3x 7

494:2x 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.

2 = 2

Therefore, the value for common factors is 2.

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 = 14212380/(1x2)

LCM = 14212380/2

LCM = 7106190

Thus, we can understand that the LCM of 685,42,494 is 7106190.

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

• LCM of 604, 64, 555
• LCM of 756, 17, 709
