The LCM of 417,390,387,833,924 is 128155367340.
Find LCM of 417,390,387,833,924 with Prime Factorization
2 | 417, 390, 387, 833, 924 |
3 | 417, 195, 387, 833, 462 |
7 | 139, 65, 129, 833, 154 |
139, 65, 129, 119, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 139 x 65 x 129 x 119 x 22 = 128155367340
Therefore, the lowest common multiple of 417,390,387,833,924 is 128155367340.
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.
417 x 390 x 387 x 833 x 924 = 48442728854520
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.
417 : 1, 3, 139, 417
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
387 : 1, 3, 9, 43, 129, 387
833 : 1, 7, 17, 49, 119, 833
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,390,387,833,924, is 1.
Now, the common factors can be found like this.
417:3x 139
390:2x 3x 5x 13
387:3x 3x 43
833:7x 7x 17
924:2x 2x 3x 7x 11
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 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 48442728854520/(1x378)
LCM = 48442728854520/378
LCM = 128155367340
Thus, we can understand that the LCM of 417,390,387,833,924 is 128155367340.
