Given numbers are 407,407,750,421

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

The LCM of 407,407,750,421 is 128510250.

Find LCM of 407,407,750,421 with Prime Factorization

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

11 x 37 x 1 x 1 x 750 x 421 = 128510250

Therefore, the lowest common multiple of 407,407,750,421 is 128510250.

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 407 x 750 x 421 = 52303671750

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

407 : 1, 11, 37, 407

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,407,750,421, is 1.

Now, the common factors can be found like this.

407:11x 37

407:11x 37

750:2x 3x 5x 5x 5

421:421

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

11x 37 = 407

Therefore, the value for common factors is 407.

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 = 52303671750/(1x407)

LCM = 52303671750/407

LCM = 128510250

Thus, we can understand that the LCM of 407,407,750,421 is 128510250.
