Given numbers are 248,682,378,962,221

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

The LCM of 248,682,378,962,221 is 4215995784.

Find LCM of 248,682,378,962,221 with Prime Factorization

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

2 x 13 x 31 x 4 x 11 x 189 x 37 x 17 = 4215995784

Therefore, the lowest common multiple of 248,682,378,962,221 is 4215995784.

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.

248 x 682 x 378 x 962 x 221 = 13592370407616

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.

248 : 1, 2, 4, 8, 31, 62, 124, 248

682 : 1, 2, 11, 22, 31, 62, 341, 682

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

962 : 1, 2, 13, 26, 37, 74, 481, 962

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,682,378,962,221, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

682:2x 11x 31

378:2x 3x 3x 3x 7

962:2x 13x 37

221:13x 17

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

2x 2x 2x 13x 31 = 3224

Therefore, the value for common factors is 3224.

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 = 13592370407616/(1x3224)

LCM = 13592370407616/3224

LCM = 4215995784

Thus, we can understand that the LCM of 248,682,378,962,221 is 4215995784.
