Find LCM of 711,520,945,351,849 with Prime Factorization
| 3 | 711, 520, 945, 351, 849 |
| 3 | 237, 520, 315, 117, 283 |
| 3 | 79, 520, 105, 39, 283 |
| 5 | 79, 520, 35, 13, 283 |
| 13 | 79, 104, 7, 13, 283 |
| 79, 8, 7, 1, 283 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 13 x 79 x 8 x 7 x 1 x 283 = 2197245960
Therefore, the lowest common multiple of 711,520,945,351,849 is 2197245960.
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.
711 x 520 x 945 x 351 x 849 = 104116499814600
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.
711 : 1, 3, 9, 79, 237, 711
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
351 : 1, 3, 9, 13, 27, 39, 117, 351
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,520,945,351,849, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
520:2x 2x 2x 5x 13
945:3x 3x 3x 5x 7
351:3x 3x 3x 13
849:3x 283
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 3x 3x 3x 5x 13 = 47385
Therefore, the value for common factors is 47385.
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 = 104116499814600/(1x47385)
LCM = 104116499814600/47385
LCM = 2197245960
Thus, we can understand that the LCM of 711,520,945,351,849 is 2197245960.
