Given numbers are 407,89,220

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

The LCM of 407,89,220 is 724460.

Find LCM of 407,89,220 with Prime Factorization

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

11 x 37 x 89 x 20 = 724460

Therefore, the lowest common multiple of 407,89,220 is 724460.

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 89 x 220 = 7969060

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

89 : 1, 89

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,89,220, is 1.

Now, the common factors can be found like this.

407:11x 37

89:89

220:2x 2x 5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 7969060/(1x11)

LCM = 7969060/11

LCM = 724460

Thus, we can understand that the LCM of 407,89,220 is 724460.
