Find LCM of 696,784,931,961 with Prime Factorization
| 2 | 696, 784, 931, 961 |
| 2 | 348, 392, 931, 961 |
| 2 | 174, 196, 931, 961 |
| 7 | 87, 98, 931, 961 |
| 7 | 87, 14, 133, 961 |
| 87, 2, 19, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 87 x 2 x 19 x 961 = 1245409872
Therefore, the lowest common multiple of 696,784,931,961 is 1245409872.
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.
696 x 784 x 931 x 961 = 488200669824
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.
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
931 : 1, 7, 19, 49, 133, 931
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 696,784,931,961, is 1.
Now, the common factors can be found like this.
696:2x 2x 2x 3x 29
784:2x 2x 2x 2x 7x 7
931:7x 7x 19
961:31x 31
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 488200669824/(1x392)
LCM = 488200669824/392
LCM = 1245409872
Thus, we can understand that the LCM of 696,784,931,961 is 1245409872.
