Find LCM of 684,115,520,988,940 with Prime Factorization
2 | 684, 115, 520, 988, 940 |
2 | 342, 115, 260, 494, 470 |
5 | 171, 115, 130, 247, 235 |
13 | 171, 23, 26, 247, 47 |
19 | 171, 23, 2, 19, 47 |
9, 23, 2, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 19 x 9 x 23 x 2 x 1 x 47 = 96122520
Therefore, the lowest common multiple of 684,115,520,988,940 is 96122520.
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.
684 x 115 x 520 x 988 x 940 = 37987619904000
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
115 : 1, 5, 23, 115
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,115,520,988,940, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
115:5x 23
520:2x 2x 2x 5x 13
988:2x 2x 13x 19
940:2x 2x 5x 47
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 2x 5x 5x 13x 19 = 395200
Therefore, the value for common factors is 395200.
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 = 37987619904000/(1x395200)
LCM = 37987619904000/395200
LCM = 96122520
Thus, we can understand that the LCM of 684,115,520,988,940 is 96122520.
