Find LCM of 777,490,238,867,578 with Prime Factorization
| 2 | 777, 490, 238, 867, 578 |
| 3 | 777, 245, 119, 867, 289 |
| 7 | 259, 245, 119, 289, 289 |
| 17 | 37, 35, 17, 289, 289 |
| 17 | 37, 35, 1, 17, 17 |
| 37, 35, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 17 x 37 x 35 x 1 x 1 x 1 = 15718710
Therefore, the lowest common multiple of 777,490,238,867,578 is 15718710.
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.
777 x 490 x 238 x 867 x 578 = 45408901071240
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
238 : 1, 2, 7, 14, 17, 34, 119, 238
867 : 1, 3, 17, 51, 289, 867
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,490,238,867,578, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
490:2x 5x 7x 7
238:2x 7x 17
867:3x 17x 17
578:2x 17x 17
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 7x 7x 17x 17x 17 = 2888844
Therefore, the value for common factors is 2888844.
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 = 45408901071240/(1x2888844)
LCM = 45408901071240/2888844
LCM = 15718710
Thus, we can understand that the LCM of 777,490,238,867,578 is 15718710.
