Find LCM of 945,216,707,691,108 with Prime Factorization
| 2 | 945, 216, 707, 691, 108 |
| 2 | 945, 108, 707, 691, 54 |
| 3 | 945, 27, 707, 691, 54 |
| 3 | 315, 9, 707, 691, 18 |
| 3 | 105, 3, 707, 691, 6 |
| 7 | 35, 1, 707, 691, 2 |
| 5, 1, 101, 691, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 5 x 1 x 101 x 691 x 2 = 527619960
Therefore, the lowest common multiple of 945,216,707,691,108 is 527619960.
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.
945 x 216 x 707 x 691 x 108 = 10769778623520
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
707 : 1, 7, 101, 707
691 : 1, 691
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,216,707,691,108, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
216:2x 2x 2x 3x 3x 3
707:7x 101
691:691
108:2x 2x 3x 3x 3
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 3x 3x 3x 3x 3x 7 = 20412
Therefore, the value for common factors is 20412.
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 = 10769778623520/(1x20412)
LCM = 10769778623520/20412
LCM = 527619960
Thus, we can understand that the LCM of 945,216,707,691,108 is 527619960.
