Given numbers are 406,870,274,420

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

The LCM of 406,870,274,420 is 1668660.

Find LCM of 406,870,274,420 with Prime Factorization

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

2 x 3 x 5 x 7 x 29 x 1 x 1 x 137 x 2 = 1668660

Therefore, the lowest common multiple of 406,870,274,420 is 1668660.

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 870 x 274 x 420 = 40648557600

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

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

274 : 1, 2, 137, 274

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,870,274,420, is 2.

Now, the common factors can be found like this.

406:2x 7x 29

870:2x 3x 5x 29

274:2x 137

420:2x 2x 3x 5x 7

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 3x 5x 7x 29 = 12180

Therefore, the value for common factors is 12180.

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 = 40648557600/(2x12180)

LCM = 40648557600/24360

LCM = 1668660

Thus, we can understand that the LCM of 406,870,274,420 is 1668660.
