Calculate the LCM of 901,781,555,215

Given numbers are 901,781,555,215

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

The LCM of 901,781,555,215 is 16793347065.

Find LCM of 901,781,555,215 with Prime Factorization


5 901, 781, 555, 215
901, 781, 111, 43

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

5 x 901 x 781 x 111 x 43 = 16793347065

Therefore, the lowest common multiple of 901,781,555,215 is 16793347065.

LCM Formula to Find Lowest Common Multiple of 901,781,555,215

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.

901 x 781 x 555 x 215 = 83966735325

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.

901 : 1, 17, 53, 901

781 : 1, 11, 71, 781

555 : 1, 3, 5, 15, 37, 111, 185, 555

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,781,555,215, is 1.

Now, the common factors can be found like this.

901:17x 53

781:11x 71

555:3x 5x 37

215:5x 43

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

5 = 5

Therefore, the value for common factors is 5.

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 = 83966735325/(1x5)

LCM = 83966735325/5

LCM = 16793347065

Thus, we can understand that the LCM of 901,781,555,215 is 16793347065.
