Given numbers are 172,905,989,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,905,989,591 is 2115886380.
Find LCM of 172,905,989,591 with Prime Factorization
43 | 172, 905, 989, 591 |
4, 905, 23, 591 |
Multiply the prime numbers at the bottom and the left side.
43 x 4 x 905 x 23 x 591 = 2115886380
Therefore, the lowest common multiple of 172,905,989,591 is 2115886380.
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.
172 x 905 x 989 x 591 = 90983114340
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.
172 : 1, 2, 4, 43, 86, 172
905 : 1, 5, 181, 905
989 : 1, 23, 43, 989
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,905,989,591, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
905:5x 181
989:23x 43
591:3x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 90983114340/(1x43)
LCM = 90983114340/43
LCM = 2115886380
Thus, we can understand that the LCM of 172,905,989,591 is 2115886380.
