The LCM of 896,787,644,560 is 81092480.
Find LCM of 896,787,644,560 with Prime Factorization
| 2 | 896, 787, 644, 560 |
| 2 | 448, 787, 322, 280 |
| 2 | 224, 787, 161, 140 |
| 2 | 112, 787, 161, 70 |
| 7 | 56, 787, 161, 35 |
| 8, 787, 23, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 8 x 787 x 23 x 5 = 81092480
Therefore, the lowest common multiple of 896,787,644,560 is 81092480.
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.
896 x 787 x 644 x 560 = 254306017280
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
787 : 1, 787
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,787,644,560, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
787:787
644:2x 2x 7x 23
560:2x 2x 2x 2x 5x 7
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 2x 7x 7 = 3136
Therefore, the value for common factors is 3136.
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 = 254306017280/(1x3136)
LCM = 254306017280/3136
LCM = 81092480
Thus, we can understand that the LCM of 896,787,644,560 is 81092480.
