Given numbers are 789,905,564,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,905,564,380 is 2550568740.
Find LCM of 789,905,564,380 with Prime Factorization
| 2 | 789, 905, 564, 380 |
| 2 | 789, 905, 282, 190 |
| 3 | 789, 905, 141, 95 |
| 5 | 263, 905, 47, 95 |
| 263, 181, 47, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 263 x 181 x 47 x 19 = 2550568740
Therefore, the lowest common multiple of 789,905,564,380 is 2550568740.
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 905 x 564 x 380 = 153034124400
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
905 : 1, 5, 181, 905
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,905,564,380, is 1.
Now, the common factors can be found like this.
789:3x 263
905:5x 181
564:2x 2x 3x 47
380:2x 2x 5x 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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 153034124400/(1x60)
LCM = 153034124400/60
LCM = 2550568740
Thus, we can understand that the LCM of 789,905,564,380 is 2550568740.
