The LCM of 191,423,783,957 is 77318901.
Find LCM of 191,423,783,957 with Prime Factorization
| 3 | 191, 423, 783, 957 |
| 3 | 191, 141, 261, 319 |
| 29 | 191, 47, 87, 319 |
| 191, 47, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 191 x 47 x 3 x 11 = 77318901
Therefore, the lowest common multiple of 191,423,783,957 is 77318901.
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.
191 x 423 x 783 x 957 = 60540699483
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.
191 : 1, 191
423 : 1, 3, 9, 47, 141, 423
783 : 1, 3, 9, 27, 29, 87, 261, 783
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,423,783,957, is 1.
Now, the common factors can be found like this.
191:191
423:3x 3x 47
783:3x 3x 3x 29
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 29 = 783
Therefore, the value for common factors is 783.
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 = 60540699483/(1x783)
LCM = 60540699483/783
LCM = 77318901
Thus, we can understand that the LCM of 191,423,783,957 is 77318901.
