The LCM of 663,935,786,968 is 420368520.
Find LCM of 663,935,786,968 with Prime Factorization
| 2 | 663, 935, 786, 968 |
| 3 | 663, 935, 393, 484 |
| 11 | 221, 935, 131, 484 |
| 17 | 221, 85, 131, 44 |
| 13, 5, 131, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 13 x 5 x 131 x 44 = 420368520
Therefore, the lowest common multiple of 663,935,786,968 is 420368520.
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.
663 x 935 x 786 x 968 = 471653479440
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
935 : 1, 5, 11, 17, 55, 85, 187, 935
786 : 1, 2, 3, 6, 131, 262, 393, 786
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,935,786,968, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
935:5x 11x 17
786:2x 3x 131
968:2x 2x 2x 11x 11
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 11x 17 = 1122
Therefore, the value for common factors is 1122.
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 = 471653479440/(1x1122)
LCM = 471653479440/1122
LCM = 420368520
Thus, we can understand that the LCM of 663,935,786,968 is 420368520.
