Given numbers are 4,989,688,741
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4,989,688,741 is 11725584.
Find LCM of 4,989,688,741 with Prime Factorization
| 2 | 4, 989, 688, 741 |
| 2 | 2, 989, 344, 741 |
| 43 | 1, 989, 172, 741 |
| 1, 23, 4, 741 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 1 x 23 x 4 x 741 = 11725584
Therefore, the lowest common multiple of 4,989,688,741 is 11725584.
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.
4 x 989 x 688 x 741 = 2016800448
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.
4 : 1, 2, 4
989 : 1, 23, 43, 989
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,989,688,741, is 1.
Now, the common factors can be found like this.
4:2x 2
989:23x 43
688:2x 2x 2x 2x 43
741:3x 13x 19
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 43 = 172
Therefore, the value for common factors is 172.
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 = 2016800448/(1x172)
LCM = 2016800448/172
LCM = 11725584
Thus, we can understand that the LCM of 4,989,688,741 is 11725584.
