Calculate the LCM of 845,447,447,917,423

Given numbers are 845,447,447,917,423

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

The LCM of 845,447,447,917,423 is 48837416355.

Find LCM of 845,447,447,917,423 with Prime Factorization


3 845, 447, 447, 917, 423
149 845, 149, 149, 917, 141
845, 1, 1, 917, 141

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

3 x 149 x 845 x 1 x 1 x 917 x 141 = 48837416355

Therefore, the lowest common multiple of 845,447,447,917,423 is 48837416355.

LCM Formula to Find Lowest Common Multiple of 845,447,447,917,423

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.

845 x 447 x 447 x 917 x 423 = 65490975332055

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.

845 : 1, 5, 13, 65, 169, 845

447 : 1, 3, 149, 447

447 : 1, 3, 149, 447

917 : 1, 7, 131, 917

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,447,447,917,423, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

447:3x 149

447:3x 149

917:7x 131

423:3x 3x 47

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

3x 3x 149 = 1341

Therefore, the value for common factors is 1341.

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 = 65490975332055/(1x1341)

LCM = 65490975332055/1341

LCM = 48837416355

Thus, we can understand that the LCM of 845,447,447,917,423 is 48837416355.
