Given numbers are 745,778,591,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,778,591,389 is 342549510.
Find LCM of 745,778,591,389 with Prime Factorization
| 389 | 745, 778, 591, 389 |
| 745, 2, 591, 1 |
Multiply the prime numbers at the bottom and the left side.
389 x 745 x 2 x 591 x 1 = 342549510
Therefore, the lowest common multiple of 745,778,591,389 is 342549510.
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.
745 x 778 x 591 x 389 = 133251759390
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.
745 : 1, 5, 149, 745
778 : 1, 2, 389, 778
591 : 1, 3, 197, 591
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,778,591,389, is 1.
Now, the common factors can be found like this.
745:5x 149
778:2x 389
591:3x 197
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
389 = 389
Therefore, the value for common factors is 389.
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 = 133251759390/(1x389)
LCM = 133251759390/389
LCM = 342549510
Thus, we can understand that the LCM of 745,778,591,389 is 342549510.
