Given numbers are 847,121,737,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,121,737,815 is 46250435.
Find LCM of 847,121,737,815 with Prime Factorization
| 11 | 847, 121, 737, 815 |
| 11 | 77, 11, 67, 815 |
| 7, 1, 67, 815 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 7 x 1 x 67 x 815 = 46250435
Therefore, the lowest common multiple of 847,121,737,815 is 46250435.
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.
847 x 121 x 737 x 815 = 61559328985
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.
847 : 1, 7, 11, 77, 121, 847
121 : 1, 11, 121
737 : 1, 11, 67, 737
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,121,737,815, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
121:11x 11
737:11x 67
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11x 11 = 1331
Therefore, the value for common factors is 1331.
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 = 61559328985/(1x1331)
LCM = 61559328985/1331
LCM = 46250435
Thus, we can understand that the LCM of 847,121,737,815 is 46250435.
