Given numbers are 397,507,861,205,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,507,861,205,922 is 266306206530.
Find LCM of 397,507,861,205,922 with Prime Factorization
| 3 | 397, 507, 861, 205, 922 |
| 41 | 397, 169, 287, 205, 922 |
| 397, 169, 7, 5, 922 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 397 x 169 x 7 x 5 x 922 = 266306206530
Therefore, the lowest common multiple of 397,507,861,205,922 is 266306206530.
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.
397 x 507 x 861 x 205 x 922 = 32755663403190
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.
397 : 1, 397
507 : 1, 3, 13, 39, 169, 507
861 : 1, 3, 7, 21, 41, 123, 287, 861
205 : 1, 5, 41, 205
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,507,861,205,922, is 1.
Now, the common factors can be found like this.
397:397
507:3x 13x 13
861:3x 7x 41
205:5x 41
922:2x 461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 32755663403190/(1x123)
LCM = 32755663403190/123
LCM = 266306206530
Thus, we can understand that the LCM of 397,507,861,205,922 is 266306206530.
