Given numbers are 21,731,658

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

The LCM of 21,731,658 is 1442994.

Find LCM of 21,731,658 with Prime Factorization

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

7 x 3 x 731 x 94 = 1442994

Therefore, the lowest common multiple of 21,731,658 is 1442994.

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.

21 x 731 x 658 = 10100958

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.

21 : 1, 3, 7, 21

731 : 1, 17, 43, 731

658 : 1, 2, 7, 14, 47, 94, 329, 658

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 21,731,658, is 1.

Now, the common factors can be found like this.

21:3x 7

731:17x 43

658:2x 7x 47

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

7 = 7

Therefore, the value for common factors is 7.

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 = 10100958/(1x7)

LCM = 10100958/7

LCM = 1442994

Thus, we can understand that the LCM of 21,731,658 is 1442994.

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

• LCM of 32, 221, 247
• LCM of 46, 830, 936
