Find LCM of 972,285,343,359,819 with Prime Factorization
| 3 | 972, 285, 343, 359, 819 |
| 3 | 324, 95, 343, 359, 273 |
| 7 | 108, 95, 343, 359, 91 |
| 108, 95, 49, 359, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 108 x 95 x 49 x 359 x 13 = 147816117540
Therefore, the lowest common multiple of 972,285,343,359,819 is 147816117540.
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.
972 x 285 x 343 x 359 x 819 = 27937246215060
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
285 : 1, 3, 5, 15, 19, 57, 95, 285
343 : 1, 7, 49, 343
359 : 1, 359
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,285,343,359,819, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
285:3x 5x 19
343:7x 7x 7
359:359
819:3x 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.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 27937246215060/(1x189)
LCM = 27937246215060/189
LCM = 147816117540
Thus, we can understand that the LCM of 972,285,343,359,819 is 147816117540.
