Find LCM of 788,567,747,808,421 with Prime Factorization
| 2 | 788, 567, 747, 808, 421 |
| 2 | 394, 567, 747, 404, 421 |
| 3 | 197, 567, 747, 202, 421 |
| 3 | 197, 189, 249, 202, 421 |
| 197, 63, 83, 202, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 197 x 63 x 83 x 202 x 421 = 3153703310856
Therefore, the lowest common multiple of 788,567,747,808,421 is 3153703310856.
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.
788 x 567 x 747 x 808 x 421 = 113533319190816
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.
788 : 1, 2, 4, 197, 394, 788
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
747 : 1, 3, 9, 83, 249, 747
808 : 1, 2, 4, 8, 101, 202, 404, 808
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,567,747,808,421, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
567:3x 3x 3x 3x 7
747:3x 3x 83
808:2x 2x 2x 101
421:421
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 113533319190816/(1x36)
LCM = 113533319190816/36
LCM = 3153703310856
Thus, we can understand that the LCM of 788,567,747,808,421 is 3153703310856.
