The LCM of 462,691,558,257,678 is 862212943746.
Find LCM of 462,691,558,257,678 with Prime Factorization
| 2 | 462, 691, 558, 257, 678 |
| 3 | 231, 691, 279, 257, 339 |
| 77, 691, 93, 257, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 77 x 691 x 93 x 257 x 113 = 862212943746
Therefore, the lowest common multiple of 462,691,558,257,678 is 862212943746.
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.
462 x 691 x 558 x 257 x 678 = 31039665974856
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
691 : 1, 691
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
257 : 1, 257
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,691,558,257,678, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
691:691
558:2x 3x 3x 31
257:257
678:2x 3x 113
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 31039665974856/(1x36)
LCM = 31039665974856/36
LCM = 862212943746
Thus, we can understand that the LCM of 462,691,558,257,678 is 862212943746.
