Find LCM of 774,392,884,680 with Prime Factorization
| 2 | 774, 392, 884, 680 |
| 2 | 387, 196, 442, 340 |
| 2 | 387, 98, 221, 170 |
| 17 | 387, 49, 221, 85 |
| 387, 49, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 387 x 49 x 13 x 5 = 167632920
Therefore, the lowest common multiple of 774,392,884,680 is 167632920.
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 392 x 884 x 680 = 182384616960
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
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,392,884,680, is 2.
Now, the common factors can be found like this.
774:2x 3x 3x 43
392:2x 2x 2x 7x 7
884:2x 2x 13x 17
680:2x 2x 2x 5x 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 2x 2x 2x 17 = 544
Therefore, the value for common factors is 544.
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 = 182384616960/(2x544)
LCM = 182384616960/1088
LCM = 167632920
Thus, we can understand that the LCM of 774,392,884,680 is 167632920.
