Given numbers are 739,645,989,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 739,645,989,828 is 131556780.
Find LCM of 739,645,989,828 with Prime Factorization
| 3 | 739, 645, 989, 828 |
| 23 | 739, 215, 989, 276 |
| 43 | 739, 215, 43, 12 |
| 739, 5, 1, 12 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 43 x 739 x 5 x 1 x 12 = 131556780
Therefore, the lowest common multiple of 739,645,989,828 is 131556780.
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.
739 x 645 x 989 x 828 = 390328966260
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.
739 : 1, 739
645 : 1, 3, 5, 15, 43, 129, 215, 645
989 : 1, 23, 43, 989
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 739,645,989,828, is 1.
Now, the common factors can be found like this.
739:739
645:3x 5x 43
989:23x 43
828:2x 2x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23x 43 = 2967
Therefore, the value for common factors is 2967.
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 = 390328966260/(1x2967)
LCM = 390328966260/2967
LCM = 131556780
Thus, we can understand that the LCM of 739,645,989,828 is 131556780.
