Given numbers are 715,904,206,862,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,904,206,862,764 is 5480527160680.
Find LCM of 715,904,206,862,764 with Prime Factorization
| 2 | 715, 904, 206, 862, 764 |
| 2 | 715, 452, 103, 431, 382 |
| 715, 226, 103, 431, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 715 x 226 x 103 x 431 x 191 = 5480527160680
Therefore, the lowest common multiple of 715,904,206,862,764 is 5480527160680.
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.
715 x 904 x 206 x 862 x 764 = 87688434570880
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
904 : 1, 2, 4, 8, 113, 226, 452, 904
206 : 1, 2, 103, 206
862 : 1, 2, 431, 862
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,904,206,862,764, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
904:2x 2x 2x 113
206:2x 103
862:2x 431
764:2x 2x 191
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 87688434570880/(1x16)
LCM = 87688434570880/16
LCM = 5480527160680
Thus, we can understand that the LCM of 715,904,206,862,764 is 5480527160680.
