Given numbers are 473,418,407,423

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

The LCM of 473,418,407,423 is 281311074.

Find LCM of 473,418,407,423 with Prime Factorization

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

11 x 43 x 38 x 37 x 423 = 281311074

Therefore, the lowest common multiple of 473,418,407,423 is 281311074.

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.

473 x 418 x 407 x 423 = 34038639954

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.

473 : 1, 11, 43, 473

418 : 1, 2, 11, 19, 22, 38, 209, 418

407 : 1, 11, 37, 407

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,418,407,423, is 1.

Now, the common factors can be found like this.

473:11x 43

418:2x 11x 19

407:11x 37

423:3x 3x 47

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 34038639954/(1x121)

LCM = 34038639954/121

LCM = 281311074

Thus, we can understand that the LCM of 473,418,407,423 is 281311074.
