Find LCM of 784,336,849,789,123 with Prime Factorization
| 2 | 784, 336, 849, 789, 123 |
| 2 | 392, 168, 849, 789, 123 |
| 2 | 196, 84, 849, 789, 123 |
| 2 | 98, 42, 849, 789, 123 |
| 3 | 49, 21, 849, 789, 123 |
| 7 | 49, 7, 283, 263, 41 |
| 1, 7, 283, 263, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 1 x 7 x 283 x 263 x 41 = 7177337328
Therefore, the lowest common multiple of 784,336,849,789,123 is 7177337328.
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 336 x 849 x 789 x 123 = 21704268079872
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
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
849 : 1, 3, 283, 849
789 : 1, 3, 263, 789
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,336,849,789,123, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
336:2x 2x 2x 2x 3x 7
849:3x 283
789:3x 263
123:3x 41
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 3x 3x 3x 7 = 3024
Therefore, the value for common factors is 3024.
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 = 21704268079872/(1x3024)
LCM = 21704268079872/3024
LCM = 7177337328
Thus, we can understand that the LCM of 784,336,849,789,123 is 7177337328.
