Find LCM of 972,643,385,187,935 with Prime Factorization
| 5 | 972, 643, 385, 187, 935 |
| 11 | 972, 643, 77, 187, 187 |
| 17 | 972, 643, 7, 17, 17 |
| 972, 643, 7, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 17 x 972 x 643 x 7 x 1 x 1 = 4090598820
Therefore, the lowest common multiple of 972,643,385,187,935 is 4090598820.
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.
972 x 643 x 385 x 187 x 935 = 42071808863700
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
643 : 1, 643
385 : 1, 5, 7, 11, 35, 55, 77, 385
187 : 1, 11, 17, 187
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,643,385,187,935, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
643:643
385:5x 7x 11
187:11x 17
935:5x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11x 17 = 10285
Therefore, the value for common factors is 10285.
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 = 42071808863700/(1x10285)
LCM = 42071808863700/10285
LCM = 4090598820
Thus, we can understand that the LCM of 972,643,385,187,935 is 4090598820.
