Find LCM of 556,300,800,721,704 with Prime Factorization
| 2 | 556, 300, 800, 721, 704 |
| 2 | 278, 150, 400, 721, 352 |
| 2 | 139, 75, 200, 721, 176 |
| 2 | 139, 75, 100, 721, 88 |
| 2 | 139, 75, 50, 721, 44 |
| 5 | 139, 75, 25, 721, 22 |
| 5 | 139, 15, 5, 721, 22 |
| 139, 3, 1, 721, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 5 x 139 x 3 x 1 x 721 x 22 = 5291563200
Therefore, the lowest common multiple of 556,300,800,721,704 is 5291563200.
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.
556 x 300 x 800 x 721 x 704 = 67732008960000
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.
556 : 1, 2, 4, 139, 278, 556
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
721 : 1, 7, 103, 721
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,300,800,721,704, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
300:2x 2x 3x 5x 5
800:2x 2x 2x 2x 2x 5x 5
721:7x 103
704:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 2x 5x 5 = 12800
Therefore, the value for common factors is 12800.
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 = 67732008960000/(1x12800)
LCM = 67732008960000/12800
LCM = 5291563200
Thus, we can understand that the LCM of 556,300,800,721,704 is 5291563200.
