Given numbers are 660,419,991,803,419

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

The LCM of 660,419,991,803,419 is 20005733220.

Find LCM of 660,419,991,803,419 with Prime Factorization

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

11 x 419 x 60 x 1 x 991 x 73 x 1 = 20005733220

Therefore, the lowest common multiple of 660,419,991,803,419 is 20005733220.

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.

660 x 419 x 991 x 803 x 419 = 92206424410980

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

419 : 1, 419

991 : 1, 991

803 : 1, 11, 73, 803

419 : 1, 419

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,419,991,803,419, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

419:419

991:991

803:11x 73

419:419

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

11x 419 = 4609

Therefore, the value for common factors is 4609.

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 = 92206424410980/(1x4609)

LCM = 92206424410980/4609

LCM = 20005733220

Thus, we can understand that the LCM of 660,419,991,803,419 is 20005733220.
