Given numbers are 839,670,165,649,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,670,165,649,788 is 431220041340.
Find LCM of 839,670,165,649,788 with Prime Factorization
| 2 | 839, 670, 165, 649, 788 |
| 5 | 839, 335, 165, 649, 394 |
| 11 | 839, 67, 33, 649, 394 |
| 839, 67, 3, 59, 394 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 839 x 67 x 3 x 59 x 394 = 431220041340
Therefore, the lowest common multiple of 839,670,165,649,788 is 431220041340.
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.
839 x 670 x 165 x 649 x 788 = 47434204547400
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.
839 : 1, 839
670 : 1, 2, 5, 10, 67, 134, 335, 670
165 : 1, 3, 5, 11, 15, 33, 55, 165
649 : 1, 11, 59, 649
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,670,165,649,788, is 1.
Now, the common factors can be found like this.
839:839
670:2x 5x 67
165:3x 5x 11
649:11x 59
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 47434204547400/(1x110)
LCM = 47434204547400/110
LCM = 431220041340
Thus, we can understand that the LCM of 839,670,165,649,788 is 431220041340.
