Given numbers are 690,164,926,249,317
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,164,926,249,317 is 689257163940.
Find LCM of 690,164,926,249,317 with Prime Factorization
| 2 | 690, 164, 926, 249, 317 |
| 3 | 345, 82, 463, 249, 317 |
| 115, 82, 463, 83, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 115 x 82 x 463 x 83 x 317 = 689257163940
Therefore, the lowest common multiple of 690,164,926,249,317 is 689257163940.
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.
690 x 164 x 926 x 249 x 317 = 8271085967280
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
164 : 1, 2, 4, 41, 82, 164
926 : 1, 2, 463, 926
249 : 1, 3, 83, 249
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,164,926,249,317, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
164:2x 2x 41
926:2x 463
249:3x 83
317:317
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 3 = 12
Therefore, the value for common factors is 12.
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 = 8271085967280/(1x12)
LCM = 8271085967280/12
LCM = 689257163940
Thus, we can understand that the LCM of 690,164,926,249,317 is 689257163940.
