Given numbers are 421,403,421,508

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

The LCM of 421,403,421,508 is 86188804.

Find LCM of 421,403,421,508 with Prime Factorization

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

421 x 1 x 403 x 1 x 508 = 86188804

Therefore, the lowest common multiple of 421,403,421,508 is 86188804.

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.

421 x 403 x 421 x 508 = 36285486484

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.

421 : 1, 421

403 : 1, 13, 31, 403

421 : 1, 421

508 : 1, 2, 4, 127, 254, 508

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,403,421,508, is 1.

Now, the common factors can be found like this.

421:421

403:13x 31

421:421

508:2x 2x 127

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

421 = 421

Therefore, the value for common factors is 421.

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 = 36285486484/(1x421)

LCM = 36285486484/421

LCM = 86188804

Thus, we can understand that the LCM of 421,403,421,508 is 86188804.
