Given numbers are 887,745,180,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 887,745,180,972 is 642312180.
Find LCM of 887,745,180,972 with Prime Factorization
| 2 | 887, 745, 180, 972 |
| 2 | 887, 745, 90, 486 |
| 3 | 887, 745, 45, 243 |
| 3 | 887, 745, 15, 81 |
| 5 | 887, 745, 5, 27 |
| 887, 149, 1, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 887 x 149 x 1 x 27 = 642312180
Therefore, the lowest common multiple of 887,745,180,972 is 642312180.
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.
887 x 745 x 180 x 972 = 115616192400
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.
887 : 1, 887
745 : 1, 5, 149, 745
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 887,745,180,972, is 1.
Now, the common factors can be found like this.
887:887
745:5x 149
180:2x 2x 3x 3x 5
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 115616192400/(1x180)
LCM = 115616192400/180
LCM = 642312180
Thus, we can understand that the LCM of 887,745,180,972 is 642312180.
