Given numbers are 968,642,428,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 968,642,428,629 is 195447912.
Find LCM of 968,642,428,629 with Prime Factorization
2 | 968, 642, 428, 629 |
2 | 484, 321, 214, 629 |
107 | 242, 321, 107, 629 |
242, 3, 1, 629 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 107 x 242 x 3 x 1 x 629 = 195447912
Therefore, the lowest common multiple of 968,642,428,629 is 195447912.
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.
968 x 642 x 428 x 629 = 167303412672
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.
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
642 : 1, 2, 3, 6, 107, 214, 321, 642
428 : 1, 2, 4, 107, 214, 428
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,642,428,629, is 1.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
642:2x 3x 107
428:2x 2x 107
629:17x 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 2x 107 = 856
Therefore, the value for common factors is 856.
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 = 167303412672/(1x856)
LCM = 167303412672/856
LCM = 195447912
Thus, we can understand that the LCM of 968,642,428,629 is 195447912.
