Given numbers are 407,66,722

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

The LCM of 407,66,722 is 881562.

Find LCM of 407,66,722 with Prime Factorization

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

2 x 11 x 37 x 3 x 361 = 881562

Therefore, the lowest common multiple of 407,66,722 is 881562.

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.

407 x 66 x 722 = 19394364

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.

407 : 1, 11, 37, 407

66 : 1, 2, 3, 6, 11, 22, 33, 66

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,66,722, is 1.

Now, the common factors can be found like this.

407:11x 37

66:2x 3x 11

722:2x 19x 19

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 19394364/(1x22)

LCM = 19394364/22

LCM = 881562

Thus, we can understand that the LCM of 407,66,722 is 881562.

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

• LCM of 840, 57, 641
• LCM of 455, 93, 291
