Given numbers are 665,296,646,806,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,296,646,806,838 is 565042801960.
Find LCM of 665,296,646,806,838 with Prime Factorization
2 | 665, 296, 646, 806, 838 |
19 | 665, 148, 323, 403, 419 |
35, 148, 17, 403, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 35 x 148 x 17 x 403 x 419 = 565042801960
Therefore, the lowest common multiple of 665,296,646,806,838 is 565042801960.
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.
665 x 296 x 646 x 806 x 838 = 85886505897920
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
296 : 1, 2, 4, 8, 37, 74, 148, 296
646 : 1, 2, 17, 19, 34, 38, 323, 646
806 : 1, 2, 13, 26, 31, 62, 403, 806
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,296,646,806,838, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
296:2x 2x 2x 37
646:2x 17x 19
806:2x 13x 31
838:2x 419
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 19 = 152
Therefore, the value for common factors is 152.
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 = 85886505897920/(1x152)
LCM = 85886505897920/152
LCM = 565042801960
Thus, we can understand that the LCM of 665,296,646,806,838 is 565042801960.
