Find LCM of 689,900,666,798,700 with Prime Factorization
| 2 | 689, 900, 666, 798, 700 |
| 2 | 689, 450, 333, 399, 350 |
| 3 | 689, 225, 333, 399, 175 |
| 3 | 689, 75, 111, 133, 175 |
| 5 | 689, 25, 37, 133, 175 |
| 5 | 689, 5, 37, 133, 35 |
| 7 | 689, 1, 37, 133, 7 |
| 689, 1, 37, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 7 x 689 x 1 x 37 x 19 x 1 = 3051512100
Therefore, the lowest common multiple of 689,900,666,798,700 is 3051512100.
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.
689 x 900 x 666 x 798 x 700 = 230694314760000
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.
689 : 1, 13, 53, 689
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,900,666,798,700, is 1.
Now, the common factors can be found like this.
689:13x 53
900:2x 2x 3x 3x 5x 5
666:2x 3x 3x 37
798:2x 3x 7x 19
700:2x 2x 5x 5x 7
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 3x 3x 3x 5x 5x 7 = 75600
Therefore, the value for common factors is 75600.
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 = 230694314760000/(1x75600)
LCM = 230694314760000/75600
LCM = 3051512100
Thus, we can understand that the LCM of 689,900,666,798,700 is 3051512100.
