Find LCM of 718,720,990,414 with Prime Factorization
2 | 718, 720, 990, 414 |
3 | 359, 360, 495, 207 |
3 | 359, 120, 165, 69 |
5 | 359, 40, 55, 23 |
359, 8, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 359 x 8 x 11 x 23 = 65395440
Therefore, the lowest common multiple of 718,720,990,414 is 65395440.
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.
718 x 720 x 990 x 414 = 211881225600
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.
718 : 1, 2, 359, 718
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,720,990,414, is 2.
Now, the common factors can be found like this.
718:2x 359
720:2x 2x 2x 2x 3x 3x 5
990:2x 3x 3x 5x 11
414:2x 3x 3x 23
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 3x 3x 3x 5 = 1620
Therefore, the value for common factors is 1620.
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 = 211881225600/(2x1620)
LCM = 211881225600/3240
LCM = 65395440
Thus, we can understand that the LCM of 718,720,990,414 is 65395440.
