Given numbers are 946,361,989,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,361,989,115 is 39273190.
Find LCM of 946,361,989,115 with Prime Factorization
| 23 | 946, 361, 989, 115 |
| 43 | 946, 361, 43, 5 |
| 22, 361, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 22 x 361 x 1 x 5 = 39273190
Therefore, the lowest common multiple of 946,361,989,115 is 39273190.
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.
946 x 361 x 989 x 115 = 38841184910
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
361 : 1, 19, 361
989 : 1, 23, 43, 989
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,361,989,115, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
361:19x 19
989:23x 43
115:5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 43 = 989
Therefore, the value for common factors is 989.
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 = 38841184910/(1x989)
LCM = 38841184910/989
LCM = 39273190
Thus, we can understand that the LCM of 946,361,989,115 is 39273190.
