Given numbers are 409,978,219,894

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

The LCM of 409,978,219,894 is 4350821754.

Find LCM of 409,978,219,894 with Prime Factorization

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

2 x 3 x 409 x 163 x 73 x 149 = 4350821754

Therefore, the lowest common multiple of 409,978,219,894 is 4350821754.

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.

409 x 978 x 219 x 894 = 78314791572

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.

409 : 1, 409

978 : 1, 2, 3, 6, 163, 326, 489, 978

219 : 1, 3, 73, 219

894 : 1, 2, 3, 6, 149, 298, 447, 894

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,978,219,894, is 1.

Now, the common factors can be found like this.

409:409

978:2x 3x 163

219:3x 73

894:2x 3x 149

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 78314791572/(1x18)

LCM = 78314791572/18

LCM = 4350821754

Thus, we can understand that the LCM of 409,978,219,894 is 4350821754.
