Find LCM of 985,749,663,376,784 with Prime Factorization
| 2 | 985, 749, 663, 376, 784 |
| 2 | 985, 749, 663, 188, 392 |
| 2 | 985, 749, 663, 94, 196 |
| 7 | 985, 749, 663, 47, 98 |
| 985, 107, 663, 47, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 985 x 107 x 663 x 47 x 14 = 2574823458480
Therefore, the lowest common multiple of 985,749,663,376,784 is 2574823458480.
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.
985 x 749 x 663 x 376 x 784 = 144190113674880
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.
985 : 1, 5, 197, 985
749 : 1, 7, 107, 749
663 : 1, 3, 13, 17, 39, 51, 221, 663
376 : 1, 2, 4, 8, 47, 94, 188, 376
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,749,663,376,784, is 1.
Now, the common factors can be found like this.
985:5x 197
749:7x 107
663:3x 13x 17
376:2x 2x 2x 47
784:2x 2x 2x 2x 7x 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 7 = 56
Therefore, the value for common factors is 56.
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 = 144190113674880/(1x56)
LCM = 144190113674880/56
LCM = 2574823458480
Thus, we can understand that the LCM of 985,749,663,376,784 is 2574823458480.
