Given numbers are 781,355,401,217

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

The LCM of 781,355,401,217 is 339801385.

Find LCM of 781,355,401,217 with Prime Factorization

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

71 x 11 x 5 x 401 x 217 = 339801385

Therefore, the lowest common multiple of 781,355,401,217 is 339801385.

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.

781 x 355 x 401 x 217 = 24125898335

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.

781 : 1, 11, 71, 781

355 : 1, 5, 71, 355

401 : 1, 401

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,355,401,217, is 1.

Now, the common factors can be found like this.

781:11x 71

355:5x 71

401:401

217:7x 31

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

71 = 71

Therefore, the value for common factors is 71.

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 = 24125898335/(1x71)

LCM = 24125898335/71

LCM = 339801385

Thus, we can understand that the LCM of 781,355,401,217 is 339801385.
