Given numbers are 407,505,242

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

The LCM of 407,505,242 is 4521770.

Find LCM of 407,505,242 with Prime Factorization

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

11 x 37 x 505 x 22 = 4521770

Therefore, the lowest common multiple of 407,505,242 is 4521770.

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 505 x 242 = 49739470

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

505 : 1, 5, 101, 505

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,505,242, is 1.

Now, the common factors can be found like this.

407:11x 37

505:5x 101

242:2x 11x 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 = 49739470/(1x11)

LCM = 49739470/11

LCM = 4521770

Thus, we can understand that the LCM of 407,505,242 is 4521770.

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

• LCM of 343, 336, 775
• LCM of 391, 462, 883
