The LCM of 678,825,521,700 is 1359966300.
Find LCM of 678,825,521,700 with Prime Factorization
| 2 | 678, 825, 521, 700 |
| 3 | 339, 825, 521, 350 |
| 5 | 113, 275, 521, 350 |
| 5 | 113, 55, 521, 70 |
| 113, 11, 521, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 113 x 11 x 521 x 14 = 1359966300
Therefore, the lowest common multiple of 678,825,521,700 is 1359966300.
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.
678 x 825 x 521 x 700 = 203994945000
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
521 : 1, 521
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 678,825,521,700, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
825:3x 5x 5x 11
521:521
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 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 203994945000/(1x150)
LCM = 203994945000/150
LCM = 1359966300
Thus, we can understand that the LCM of 678,825,521,700 is 1359966300.
