Given numbers are 311,555,663,565,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,555,663,565,781 is 3366472903365.
Find LCM of 311,555,663,565,781 with Prime Factorization
3 | 311, 555, 663, 565, 781 |
5 | 311, 185, 221, 565, 781 |
311, 37, 221, 113, 781 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 311 x 37 x 221 x 113 x 781 = 3366472903365
Therefore, the lowest common multiple of 311,555,663,565,781 is 3366472903365.
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.
311 x 555 x 663 x 565 x 781 = 50497093550475
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.
311 : 1, 311
555 : 1, 3, 5, 15, 37, 111, 185, 555
663 : 1, 3, 13, 17, 39, 51, 221, 663
565 : 1, 5, 113, 565
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,555,663,565,781, is 1.
Now, the common factors can be found like this.
311:311
555:3x 5x 37
663:3x 13x 17
565:5x 113
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 50497093550475/(1x15)
LCM = 50497093550475/15
LCM = 3366472903365
Thus, we can understand that the LCM of 311,555,663,565,781 is 3366472903365.
