Given numbers are 957,979,455,646,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,979,455,646,431 is 10790041852590.
Find LCM of 957,979,455,646,431 with Prime Factorization
11 | 957, 979, 455, 646, 431 |
87, 89, 455, 646, 431 |
Multiply the prime numbers at the bottom and the left side.
11 x 87 x 89 x 455 x 646 x 431 = 10790041852590
Therefore, the lowest common multiple of 957,979,455,646,431 is 10790041852590.
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.
957 x 979 x 455 x 646 x 431 = 118690460378490
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
979 : 1, 11, 89, 979
455 : 1, 5, 7, 13, 35, 65, 91, 455
646 : 1, 2, 17, 19, 34, 38, 323, 646
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,979,455,646,431, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
979:11x 89
455:5x 7x 13
646:2x 17x 19
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 118690460378490/(1x11)
LCM = 118690460378490/11
LCM = 10790041852590
Thus, we can understand that the LCM of 957,979,455,646,431 is 10790041852590.
