Given numbers are 969,665,992,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,665,992,169 is 5685781920.
Find LCM of 969,665,992,169 with Prime Factorization
19 | 969, 665, 992, 169 |
51, 35, 992, 169 |
Multiply the prime numbers at the bottom and the left side.
19 x 51 x 35 x 992 x 169 = 5685781920
Therefore, the lowest common multiple of 969,665,992,169 is 5685781920.
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.
969 x 665 x 992 x 169 = 108029856480
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
665 : 1, 5, 7, 19, 35, 95, 133, 665
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,665,992,169, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
665:5x 7x 19
992:2x 2x 2x 2x 2x 31
169:13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 108029856480/(1x19)
LCM = 108029856480/19
LCM = 5685781920
Thus, we can understand that the LCM of 969,665,992,169 is 5685781920.
