Find LCM of 756,684,300,537,945 with Prime Factorization
| 2 | 756, 684, 300, 537, 945 |
| 2 | 378, 342, 150, 537, 945 |
| 3 | 189, 171, 75, 537, 945 |
| 3 | 63, 57, 25, 179, 315 |
| 3 | 21, 19, 25, 179, 105 |
| 5 | 7, 19, 25, 179, 35 |
| 7 | 7, 19, 5, 179, 7 |
| 1, 19, 5, 179, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 7 x 1 x 19 x 5 x 179 x 1 = 64278900
Therefore, the lowest common multiple of 756,684,300,537,945 is 64278900.
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.
756 x 684 x 300 x 537 x 945 = 78723654408000
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
537 : 1, 3, 179, 537
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,684,300,537,945, is 3.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
684:2x 2x 3x 3x 19
300:2x 2x 3x 5x 5
537:3x 179
945:3x 3x 3x 5x 7
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 3x 3x 3x 3x 5x 7 = 408240
Therefore, the value for common factors is 408240.
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 = 78723654408000/(3x408240)
LCM = 78723654408000/1224720
LCM = 64278900
Thus, we can understand that the LCM of 756,684,300,537,945 is 64278900.
