Given numbers are 969,981,331,658
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,981,331,658 is 69012127674.
Find LCM of 969,981,331,658 with Prime Factorization
| 3 | 969, 981, 331, 658 |
| 323, 327, 331, 658 |
Multiply the prime numbers at the bottom and the left side.
3 x 323 x 327 x 331 x 658 = 69012127674
Therefore, the lowest common multiple of 969,981,331,658 is 69012127674.
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.
969 x 981 x 331 x 658 = 207036383022
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
981 : 1, 3, 9, 109, 327, 981
331 : 1, 331
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,981,331,658, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
981:3x 3x 109
331:331
658:2x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 207036383022/(1x3)
LCM = 207036383022/3
LCM = 69012127674
Thus, we can understand that the LCM of 969,981,331,658 is 69012127674.
