Find LCM of 684,980,707,540 with Prime Factorization
| 2 | 684, 980, 707, 540 |
| 2 | 342, 490, 707, 270 |
| 3 | 171, 245, 707, 135 |
| 3 | 57, 245, 707, 45 |
| 5 | 19, 245, 707, 15 |
| 7 | 19, 49, 707, 3 |
| 19, 7, 101, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 19 x 7 x 101 x 3 = 50776740
Therefore, the lowest common multiple of 684,980,707,540 is 50776740.
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 980 x 707 x 540 = 255914769600
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
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
707 : 1, 7, 101, 707
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,980,707,540, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
980:2x 2x 5x 7x 7
707:7x 101
540:2x 2x 3x 3x 3x 5
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 3x 3x 5x 7 = 5040
Therefore, the value for common factors is 5040.
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 = 255914769600/(1x5040)
LCM = 255914769600/5040
LCM = 50776740
Thus, we can understand that the LCM of 684,980,707,540 is 50776740.
