Given numbers are 903,78,691

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

The LCM of 903,78,691 is 16223298.

Find LCM of 903,78,691 with Prime Factorization

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

3 x 301 x 26 x 691 = 16223298

Therefore, the lowest common multiple of 903,78,691 is 16223298.

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.

903 x 78 x 691 = 48669894

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

78 : 1, 2, 3, 6, 13, 26, 39, 78

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,78,691, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

78:2x 3x 13

691:691

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

3 = 3

Therefore, the value for common factors is 3.

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 = 48669894/(1x3)

LCM = 48669894/3

LCM = 16223298

Thus, we can understand that the LCM of 903,78,691 is 16223298.

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

• LCM of 372, 55, 843
• LCM of 575, 82, 779
