Find LCM of 714,912,494,720 with Prime Factorization
| 2 | 714, 912, 494, 720 |
| 2 | 357, 456, 247, 360 |
| 2 | 357, 228, 247, 180 |
| 2 | 357, 114, 247, 90 |
| 3 | 357, 57, 247, 45 |
| 19 | 119, 19, 247, 15 |
| 119, 1, 13, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 19 x 119 x 1 x 13 x 15 = 21162960
Therefore, the lowest common multiple of 714,912,494,720 is 21162960.
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.
714 x 912 x 494 x 720 = 231607434240
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
494 : 1, 2, 13, 19, 26, 38, 247, 494
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,912,494,720, is 2.
Now, the common factors can be found like this.
714:2x 3x 7x 17
912:2x 2x 2x 2x 3x 19
494:2x 13x 19
720:2x 2x 2x 2x 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 2x 2x 3x 3x 19 = 5472
Therefore, the value for common factors is 5472.
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 = 231607434240/(2x5472)
LCM = 231607434240/10944
LCM = 21162960
Thus, we can understand that the LCM of 714,912,494,720 is 21162960.
