Given numbers are 684,744,308,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,744,308,961 is 101227896.
Find LCM of 684,744,308,961 with Prime Factorization
| 2 | 684, 744, 308, 961 |
| 2 | 342, 372, 154, 961 |
| 3 | 171, 186, 77, 961 |
| 31 | 57, 62, 77, 961 |
| 57, 2, 77, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 57 x 2 x 77 x 31 = 101227896
Therefore, the lowest common multiple of 684,744,308,961 is 101227896.
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.
684 x 744 x 308 x 961 = 150627109248
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,744,308,961, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
744:2x 2x 2x 3x 31
308:2x 2x 7x 11
961:31x 31
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 2x 3x 31 = 1488
Therefore, the value for common factors is 1488.
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 = 150627109248/(1x1488)
LCM = 150627109248/1488
LCM = 101227896
Thus, we can understand that the LCM of 684,744,308,961 is 101227896.
