Given numbers are 734,819,689,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 734,819,689,609 is 923961402.
Find LCM of 734,819,689,609 with Prime Factorization
| 3 | 734, 819, 689, 609 |
| 7 | 734, 273, 689, 203 |
| 13 | 734, 39, 689, 29 |
| 734, 3, 53, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 734 x 3 x 53 x 29 = 923961402
Therefore, the lowest common multiple of 734,819,689,609 is 923961402.
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.
734 x 819 x 689 x 609 = 252241462746
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.
734 : 1, 2, 367, 734
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
689 : 1, 13, 53, 689
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 734,819,689,609, is 1.
Now, the common factors can be found like this.
734:2x 367
819:3x 3x 7x 13
689:13x 53
609:3x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13 = 273
Therefore, the value for common factors is 273.
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 = 252241462746/(1x273)
LCM = 252241462746/273
LCM = 923961402
Thus, we can understand that the LCM of 734,819,689,609 is 923961402.
