The LCM of 537,311,784,756 is 1178401392.
Find LCM of 537,311,784,756 with Prime Factorization
| 2 | 537, 311, 784, 756 |
| 2 | 537, 311, 392, 378 |
| 3 | 537, 311, 196, 189 |
| 7 | 179, 311, 196, 63 |
| 179, 311, 28, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 179 x 311 x 28 x 9 = 1178401392
Therefore, the lowest common multiple of 537,311,784,756 is 1178401392.
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.
537 x 311 x 784 x 756 = 98985716928
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.
537 : 1, 3, 179, 537
311 : 1, 311
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 537,311,784,756, is 1.
Now, the common factors can be found like this.
537:3x 179
311:311
784:2x 2x 2x 2x 7x 7
756:2x 2x 3x 3x 3x 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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 98985716928/(1x84)
LCM = 98985716928/84
LCM = 1178401392
Thus, we can understand that the LCM of 537,311,784,756 is 1178401392.
