Find LCM of 684,876,972,605,380 with Prime Factorization
| 2 | 684, 876, 972, 605, 380 |
| 2 | 342, 438, 486, 605, 190 |
| 3 | 171, 219, 243, 605, 95 |
| 3 | 57, 73, 81, 605, 95 |
| 5 | 19, 73, 27, 605, 95 |
| 19 | 19, 73, 27, 121, 19 |
| 1, 73, 27, 121, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 1 x 73 x 27 x 121 x 1 = 815639220
Therefore, the lowest common multiple of 684,876,972,605,380 is 815639220.
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.
684 x 876 x 972 x 605 x 380 = 133895334355200
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
605 : 1, 5, 11, 55, 121, 605
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,876,972,605,380, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
876:2x 2x 3x 73
972:2x 2x 3x 3x 3x 3x 3
605:5x 11x 11
380:2x 2x 5x 19
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 2x 2x 3x 3x 3x 5x 19 = 164160
Therefore, the value for common factors is 164160.
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 = 133895334355200/(1x164160)
LCM = 133895334355200/164160
LCM = 815639220
Thus, we can understand that the LCM of 684,876,972,605,380 is 815639220.
