Given numbers are 979,966,943,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,966,943,656 is 310194192.
Find LCM of 979,966,943,656 with Prime Factorization
| 2 | 979, 966, 943, 656 |
| 23 | 979, 483, 943, 328 |
| 41 | 979, 21, 41, 328 |
| 979, 21, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 41 x 979 x 21 x 1 x 8 = 310194192
Therefore, the lowest common multiple of 979,966,943,656 is 310194192.
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.
979 x 966 x 943 x 656 = 585026246112
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.
979 : 1, 11, 89, 979
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
943 : 1, 23, 41, 943
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,966,943,656, is 1.
Now, the common factors can be found like this.
979:11x 89
966:2x 3x 7x 23
943:23x 41
656:2x 2x 2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 41 = 1886
Therefore, the value for common factors is 1886.
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 = 585026246112/(1x1886)
LCM = 585026246112/1886
LCM = 310194192
Thus, we can understand that the LCM of 979,966,943,656 is 310194192.
