Given numbers are 321,391,247,109,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,391,247,109,943 is 138544438773.
Find LCM of 321,391,247,109,943 with Prime Factorization
23 | 321, 391, 247, 109, 943 |
321, 17, 247, 109, 41 |
Multiply the prime numbers at the bottom and the left side.
23 x 321 x 17 x 247 x 109 x 41 = 138544438773
Therefore, the lowest common multiple of 321,391,247,109,943 is 138544438773.
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.
321 x 391 x 247 x 109 x 943 = 3186522091779
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.
321 : 1, 3, 107, 321
391 : 1, 17, 23, 391
247 : 1, 13, 19, 247
109 : 1, 109
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,391,247,109,943, is 1.
Now, the common factors can be found like this.
321:3x 107
391:17x 23
247:13x 19
109:109
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 3186522091779/(1x23)
LCM = 3186522091779/23
LCM = 138544438773
Thus, we can understand that the LCM of 321,391,247,109,943 is 138544438773.
