Find LCM of 305,437,156,969,670 with Prime Factorization
| 2 | 305, 437, 156, 969, 670 |
| 3 | 305, 437, 78, 969, 335 |
| 5 | 305, 437, 26, 323, 335 |
| 19 | 61, 437, 26, 323, 67 |
| 61, 23, 26, 17, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 61 x 23 x 26 x 17 x 67 = 23682611940
Therefore, the lowest common multiple of 305,437,156,969,670 is 23682611940.
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.
305 x 437 x 156 x 969 x 670 = 13499088805800
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.
305 : 1, 5, 61, 305
437 : 1, 19, 23, 437
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
969 : 1, 3, 17, 19, 51, 57, 323, 969
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,437,156,969,670, is 1.
Now, the common factors can be found like this.
305:5x 61
437:19x 23
156:2x 2x 3x 13
969:3x 17x 19
670:2x 5x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 19 = 570
Therefore, the value for common factors is 570.
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 = 13499088805800/(1x570)
LCM = 13499088805800/570
LCM = 23682611940
Thus, we can understand that the LCM of 305,437,156,969,670 is 23682611940.
