The LCM of 126,111,972,666 is 251748.
Find LCM of 126,111,972,666 with Prime Factorization
| 2 | 126, 111, 972, 666 |
| 3 | 63, 111, 486, 333 |
| 3 | 21, 37, 162, 111 |
| 37 | 7, 37, 54, 37 |
| 7, 1, 54, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 37 x 7 x 1 x 54 x 1 = 251748
Therefore, the lowest common multiple of 126,111,972,666 is 251748.
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.
126 x 111 x 972 x 666 = 9053865072
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
111 : 1, 3, 37, 111
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,111,972,666, is 3.
Now, the common factors can be found like this.
126:2x 3x 3x 7
111:3x 37
972:2x 2x 3x 3x 3x 3x 3
666:2x 3x 3x 37
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 3x 3x 3x 3x 37 = 11988
Therefore, the value for common factors is 11988.
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 = 9053865072/(3x11988)
LCM = 9053865072/35964
LCM = 251748
Thus, we can understand that the LCM of 126,111,972,666 is 251748.
