Given numbers are 389,724,905,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,724,905,917 is 1291301060.
Find LCM of 389,724,905,917 with Prime Factorization
181 | 389, 724, 905, 917 |
389, 4, 5, 917 |
Multiply the prime numbers at the bottom and the left side.
181 x 389 x 4 x 5 x 917 = 1291301060
Therefore, the lowest common multiple of 389,724,905,917 is 1291301060.
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.
389 x 724 x 905 x 917 = 233725491860
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.
389 : 1, 389
724 : 1, 2, 4, 181, 362, 724
905 : 1, 5, 181, 905
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,724,905,917, is 1.
Now, the common factors can be found like this.
389:389
724:2x 2x 181
905:5x 181
917:7x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
181 = 181
Therefore, the value for common factors is 181.
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 = 233725491860/(1x181)
LCM = 233725491860/181
LCM = 1291301060
Thus, we can understand that the LCM of 389,724,905,917 is 1291301060.
