Given numbers are 664,781,973,213,214

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

The LCM of 664,781,973,213,214 is 161970896472.

Find LCM of 664,781,973,213,214 with Prime Factorization

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

2 x 71 x 332 x 11 x 973 x 3 x 107 = 161970896472

Therefore, the lowest common multiple of 664,781,973,213,214 is 161970896472.

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.

664 x 781 x 973 x 213 x 214 = 22999867299024

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

781 : 1, 11, 71, 781

973 : 1, 7, 139, 973

213 : 1, 3, 71, 213

214 : 1, 2, 107, 214

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,781,973,213,214, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

781:11x 71

973:7x 139

213:3x 71

214:2x 107

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 22999867299024/(1x142)

LCM = 22999867299024/142

LCM = 161970896472

Thus, we can understand that the LCM of 664,781,973,213,214 is 161970896472.
