Find LCM of 349,820,756,546 with Prime Factorization
| 2 | 349, 820, 756, 546 |
| 2 | 349, 410, 378, 273 |
| 3 | 349, 205, 189, 273 |
| 7 | 349, 205, 63, 91 |
| 349, 205, 9, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 349 x 205 x 9 x 13 = 703144260
Therefore, the lowest common multiple of 349,820,756,546 is 703144260.
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.
349 x 820 x 756 x 546 = 118128235680
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.
349 : 1, 349
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
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
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 349,820,756,546, is 1.
Now, the common factors can be found like this.
349:349
820:2x 2x 5x 41
756:2x 2x 3x 3x 3x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 118128235680/(1x168)
LCM = 118128235680/168
LCM = 703144260
Thus, we can understand that the LCM of 349,820,756,546 is 703144260.
