Find LCM of 197,784,552,546 with Prime Factorization
| 2 | 197, 784, 552, 546 |
| 2 | 197, 392, 276, 273 |
| 2 | 197, 196, 138, 273 |
| 3 | 197, 98, 69, 273 |
| 7 | 197, 98, 23, 91 |
| 197, 14, 23, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 197 x 14 x 23 x 13 = 138539856
Therefore, the lowest common multiple of 197,784,552,546 is 138539856.
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.
197 x 784 x 552 x 546 = 46549391616
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.
197 : 1, 197
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,784,552,546, is 1.
Now, the common factors can be found like this.
197:197
784:2x 2x 2x 2x 7x 7
552:2x 2x 2x 3x 23
546:2x 3x 7x 13
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 7 = 336
Therefore, the value for common factors is 336.
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 = 46549391616/(1x336)
LCM = 46549391616/336
LCM = 138539856
Thus, we can understand that the LCM of 197,784,552,546 is 138539856.
