Given numbers are 409,473,407,403

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

The LCM of 409,473,407,403 is 2884637327.

Find LCM of 409,473,407,403 with Prime Factorization

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

11 x 409 x 43 x 37 x 403 = 2884637327

Therefore, the lowest common multiple of 409,473,407,403 is 2884637327.

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.

409 x 473 x 407 x 403 = 31731010597

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.

409 : 1, 409

473 : 1, 11, 43, 473

407 : 1, 11, 37, 407

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,473,407,403, is 1.

Now, the common factors can be found like this.

409:409

473:11x 43

407:11x 37

403:13x 31

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 = 31731010597/(1x11)

LCM = 31731010597/11

LCM = 2884637327

Thus, we can understand that the LCM of 409,473,407,403 is 2884637327.
