Find LCM of 342,788,714,987,678 with Prime Factorization
2 | 342, 788, 714, 987, 678 |
3 | 171, 394, 357, 987, 339 |
7 | 57, 394, 119, 329, 113 |
57, 394, 17, 47, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 57 x 394 x 17 x 47 x 113 = 85161948732
Therefore, the lowest common multiple of 342,788,714,987,678 is 85161948732.
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.
342 x 788 x 714 x 987 x 678 = 128764866482784
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
788 : 1, 2, 4, 197, 394, 788
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
987 : 1, 3, 7, 21, 47, 141, 329, 987
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 342,788,714,987,678, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
788:2x 2x 197
714:2x 3x 7x 17
987:3x 7x 47
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 2x 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 128764866482784/(1x1512)
LCM = 128764866482784/1512
LCM = 85161948732
Thus, we can understand that the LCM of 342,788,714,987,678 is 85161948732.
