Find LCM of 496,943,672,138 with Prime Factorization
| 2 | 496, 943, 672, 138 |
| 2 | 248, 943, 336, 69 |
| 2 | 124, 943, 168, 69 |
| 2 | 62, 943, 84, 69 |
| 3 | 31, 943, 42, 69 |
| 23 | 31, 943, 14, 23 |
| 31, 41, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 23 x 31 x 41 x 14 x 1 = 19644576
Therefore, the lowest common multiple of 496,943,672,138 is 19644576.
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.
496 x 943 x 672 x 138 = 43375223808
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.
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
943 : 1, 23, 41, 943
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,943,672,138, is 1.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
943:23x 41
672:2x 2x 2x 2x 2x 3x 7
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 23 = 2208
Therefore, the value for common factors is 2208.
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 = 43375223808/(1x2208)
LCM = 43375223808/2208
LCM = 19644576
Thus, we can understand that the LCM of 496,943,672,138 is 19644576.
