Find LCM of 666,137,340,921,816 with Prime Factorization
2 | 666, 137, 340, 921, 816 |
2 | 333, 137, 170, 921, 408 |
3 | 333, 137, 85, 921, 204 |
17 | 111, 137, 85, 307, 68 |
111, 137, 5, 307, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 111 x 137 x 5 x 307 x 4 = 19047679920
Therefore, the lowest common multiple of 666,137,340,921,816 is 19047679920.
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.
666 x 137 x 340 x 921 x 816 = 23314360222080
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.
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
137 : 1, 137
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
921 : 1, 3, 307, 921
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,137,340,921,816, is 1.
Now, the common factors can be found like this.
666:2x 3x 3x 37
137:137
340:2x 2x 5x 17
921:3x 307
816:2x 2x 2x 2x 3x 17
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 3x 3x 17 = 1224
Therefore, the value for common factors is 1224.
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 = 23314360222080/(1x1224)
LCM = 23314360222080/1224
LCM = 19047679920
Thus, we can understand that the LCM of 666,137,340,921,816 is 19047679920.
