Find LCM of 945,931,788,399,718 with Prime Factorization
| 2 | 945, 931, 788, 399, 718 |
| 3 | 945, 931, 394, 399, 359 |
| 7 | 315, 931, 394, 133, 359 |
| 19 | 45, 19, 394, 133, 359 |
| 45, 1, 394, 7, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 19 x 45 x 1 x 394 x 7 x 359 = 35555281020
Therefore, the lowest common multiple of 945,931,788,399,718 is 35555281020.
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.
945 x 931 x 788 x 399 x 718 = 198611799777720
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
931 : 1, 7, 19, 49, 133, 931
788 : 1, 2, 4, 197, 394, 788
399 : 1, 3, 7, 19, 21, 57, 133, 399
718 : 1, 2, 359, 718
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,931,788,399,718, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
931:7x 7x 19
788:2x 2x 197
399:3x 7x 19
718:2x 359
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7x 19 = 5586
Therefore, the value for common factors is 5586.
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 = 198611799777720/(1x5586)
LCM = 198611799777720/5586
LCM = 35555281020
Thus, we can understand that the LCM of 945,931,788,399,718 is 35555281020.
