Calculate the LCM of 361,419,843,978

Given numbers are 361,419,843,978

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

The LCM of 361,419,843,978 is 41568695862.

Find LCM of 361,419,843,978 with Prime Factorization


3 361, 419, 843, 978
361, 419, 281, 326

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

3 x 361 x 419 x 281 x 326 = 41568695862

Therefore, the lowest common multiple of 361,419,843,978 is 41568695862.

LCM Formula to Find Lowest Common Multiple of 361,419,843,978

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.

361 x 419 x 843 x 978 = 124706087586

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.

361 : 1, 19, 361

419 : 1, 419

843 : 1, 3, 281, 843

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,419,843,978, is 1.

Now, the common factors can be found like this.

361:19x 19

419:419

843:3x 281

978:2x 3x 163

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

3 = 3

Therefore, the value for common factors is 3.

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 = 124706087586/(1x3)

LCM = 124706087586/3

LCM = 41568695862

Thus, we can understand that the LCM of 361,419,843,978 is 41568695862.
