Find LCM of 279,784,288,756 with Prime Factorization
| 2 | 279, 784, 288, 756 |
| 2 | 279, 392, 144, 378 |
| 2 | 279, 196, 72, 189 |
| 2 | 279, 98, 36, 189 |
| 3 | 279, 49, 18, 189 |
| 3 | 93, 49, 6, 63 |
| 7 | 31, 49, 2, 21 |
| 31, 7, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 7 x 31 x 7 x 2 x 3 = 1312416
Therefore, the lowest common multiple of 279,784,288,756 is 1312416.
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.
279 x 784 x 288 x 756 = 47624951808
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.
279 : 1, 3, 9, 31, 93, 279
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
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 279,784,288,756, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
784:2x 2x 2x 2x 7x 7
288:2x 2x 2x 2x 2x 3x 3
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 2x 2x 2x 2x 3x 3x 3x 3x 7 = 36288
Therefore, the value for common factors is 36288.
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 = 47624951808/(1x36288)
LCM = 47624951808/36288
LCM = 1312416
Thus, we can understand that the LCM of 279,784,288,756 is 1312416.
