Given numbers are 789,649,340,783,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,649,340,783,782 is 1045126742220.
Find LCM of 789,649,340,783,782 with Prime Factorization
2 | 789, 649, 340, 783, 782 |
3 | 789, 649, 170, 783, 391 |
17 | 263, 649, 170, 261, 391 |
263, 649, 10, 261, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 263 x 649 x 10 x 261 x 23 = 1045126742220
Therefore, the lowest common multiple of 789,649,340,783,782 is 1045126742220.
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.
789 x 649 x 340 x 783 x 782 = 106602927706440
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.
789 : 1, 3, 263, 789
649 : 1, 11, 59, 649
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
783 : 1, 3, 9, 27, 29, 87, 261, 783
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,649,340,783,782, is 1.
Now, the common factors can be found like this.
789:3x 263
649:11x 59
340:2x 2x 5x 17
783:3x 3x 3x 29
782:2x 17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 106602927706440/(1x102)
LCM = 106602927706440/102
LCM = 1045126742220
Thus, we can understand that the LCM of 789,649,340,783,782 is 1045126742220.
