Find LCM of 832,560,721,356 with Prime Factorization
| 2 | 832, 560, 721, 356 |
| 2 | 416, 280, 721, 178 |
| 2 | 208, 140, 721, 89 |
| 2 | 104, 70, 721, 89 |
| 7 | 52, 35, 721, 89 |
| 52, 5, 103, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 52 x 5 x 103 x 89 = 266943040
Therefore, the lowest common multiple of 832,560,721,356 is 266943040.
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.
832 x 560 x 721 x 356 = 119590481920
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
721 : 1, 7, 103, 721
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,560,721,356, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
560:2x 2x 2x 2x 5x 7
721:7x 103
356:2x 2x 89
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 7 = 448
Therefore, the value for common factors is 448.
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 = 119590481920/(1x448)
LCM = 119590481920/448
LCM = 266943040
Thus, we can understand that the LCM of 832,560,721,356 is 266943040.
