Given numbers are 215,903,407,446

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

The LCM of 215,903,407,446 is 819571830.

Find LCM of 215,903,407,446 with Prime Factorization

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

43 x 5 x 21 x 407 x 446 = 819571830

Therefore, the lowest common multiple of 215,903,407,446 is 819571830.

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.

215 x 903 x 407 x 446 = 35241588690

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.

215 : 1, 5, 43, 215

903 : 1, 3, 7, 21, 43, 129, 301, 903

407 : 1, 11, 37, 407

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,903,407,446, is 1.

Now, the common factors can be found like this.

215:5x 43

903:3x 7x 43

407:11x 37

446:2x 223

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

43 = 43

Therefore, the value for common factors is 43.

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 = 35241588690/(1x43)

LCM = 35241588690/43

LCM = 819571830

Thus, we can understand that the LCM of 215,903,407,446 is 819571830.
