Find LCM of 784,744,896,849 with Prime Factorization
| 2 | 784, 744, 896, 849 |
| 2 | 392, 372, 448, 849 |
| 2 | 196, 186, 224, 849 |
| 2 | 98, 93, 112, 849 |
| 3 | 49, 93, 56, 849 |
| 7 | 49, 31, 56, 283 |
| 7, 31, 8, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 7 x 31 x 8 x 283 = 165072768
Therefore, the lowest common multiple of 784,744,896,849 is 165072768.
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.
784 x 744 x 896 x 849 = 443715600384
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,744,896,849, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
744:2x 2x 2x 3x 31
896:2x 2x 2x 2x 2x 2x 2x 7
849:3x 283
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 2x 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 443715600384/(1x2688)
LCM = 443715600384/2688
LCM = 165072768
Thus, we can understand that the LCM of 784,744,896,849 is 165072768.
