Given numbers are 386,770,452,421

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

The LCM of 386,770,452,421 is 14139647060.

Find LCM of 386,770,452,421 with Prime Factorization

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

2 x 193 x 385 x 226 x 421 = 14139647060

Therefore, the lowest common multiple of 386,770,452,421 is 14139647060.

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.

386 x 770 x 452 x 421 = 56558588240

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.

386 : 1, 2, 193, 386

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

452 : 1, 2, 4, 113, 226, 452

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,770,452,421, is 1.

Now, the common factors can be found like this.

386:2x 193

770:2x 5x 7x 11

452:2x 2x 113

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 56558588240/(1x4)

LCM = 56558588240/4

LCM = 14139647060

Thus, we can understand that the LCM of 386,770,452,421 is 14139647060.
