Find LCM of 774,220,387,867,540 with Prime Factorization
| 2 | 774, 220, 387, 867, 540 |
| 2 | 387, 110, 387, 867, 270 |
| 3 | 387, 55, 387, 867, 135 |
| 3 | 129, 55, 129, 289, 45 |
| 5 | 43, 55, 43, 289, 15 |
| 43 | 43, 11, 43, 289, 3 |
| 1, 11, 1, 289, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 43 x 1 x 11 x 1 x 289 x 3 = 73816380
Therefore, the lowest common multiple of 774,220,387,867,540 is 73816380.
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.
774 x 220 x 387 x 867 x 540 = 30852294184800
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
387 : 1, 3, 9, 43, 129, 387
867 : 1, 3, 17, 51, 289, 867
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,220,387,867,540, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
220:2x 2x 5x 11
387:3x 3x 43
867:3x 17x 17
540:2x 2x 3x 3x 3x 5
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 3x 3x 3x 3x 3x 5x 43 = 417960
Therefore, the value for common factors is 417960.
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 = 30852294184800/(1x417960)
LCM = 30852294184800/417960
LCM = 73816380
Thus, we can understand that the LCM of 774,220,387,867,540 is 73816380.
