Given numbers are 406,274,386,734,620

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

The LCM of 406,274,386,734,620 is 1221326183420.

Find LCM of 406,274,386,734,620 with Prime Factorization

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

2 x 203 x 137 x 193 x 367 x 310 = 1221326183420

Therefore, the lowest common multiple of 406,274,386,734,620 is 1221326183420.

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.

406 x 274 x 386 x 734 x 620 = 19541218934720

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

274 : 1, 2, 137, 274

386 : 1, 2, 193, 386

734 : 1, 2, 367, 734

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,274,386,734,620, is 2.

Now, the common factors can be found like this.

406:2x 7x 29

274:2x 137

386:2x 193

734:2x 367

620:2x 2x 5x 31

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 19541218934720/(2x8)

LCM = 19541218934720/16

LCM = 1221326183420

Thus, we can understand that the LCM of 406,274,386,734,620 is 1221326183420.
