Find LCM of 561,121,726,455,376 with Prime Factorization
2 | 561, 121, 726, 455, 376 |
3 | 561, 121, 363, 455, 188 |
11 | 187, 121, 121, 455, 188 |
11 | 17, 11, 11, 455, 188 |
17, 1, 1, 455, 188 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 11 x 17 x 1 x 1 x 455 x 188 = 1055734680
Therefore, the lowest common multiple of 561,121,726,455,376 is 1055734680.
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.
561 x 121 x 726 x 455 x 376 = 8431097154480
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
121 : 1, 11, 121
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
455 : 1, 5, 7, 13, 35, 65, 91, 455
376 : 1, 2, 4, 8, 47, 94, 188, 376
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,121,726,455,376, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
121:11x 11
726:2x 3x 11x 11
455:5x 7x 13
376:2x 2x 2x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 11x 11 = 7986
Therefore, the value for common factors is 7986.
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 = 8431097154480/(1x7986)
LCM = 8431097154480/7986
LCM = 1055734680
Thus, we can understand that the LCM of 561,121,726,455,376 is 1055734680.
