Find LCM of 726,436,284,847 with Prime Factorization
| 2 | 726, 436, 284, 847 |
| 2 | 363, 218, 142, 847 |
| 11 | 363, 109, 71, 847 |
| 11 | 33, 109, 71, 77 |
| 3, 109, 71, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 11 x 3 x 109 x 71 x 7 = 78659196
Therefore, the lowest common multiple of 726,436,284,847 is 78659196.
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.
726 x 436 x 284 x 847 = 76142101728
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
436 : 1, 2, 4, 109, 218, 436
284 : 1, 2, 4, 71, 142, 284
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,436,284,847, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
436:2x 2x 109
284:2x 2x 71
847:7x 11x 11
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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 76142101728/(1x968)
LCM = 76142101728/968
LCM = 78659196
Thus, we can understand that the LCM of 726,436,284,847 is 78659196.
