Given numbers are 491,561,867,978,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,561,867,978,667 is 1018208477814.
Find LCM of 491,561,867,978,667 with Prime Factorization
3 | 491, 561, 867, 978, 667 |
17 | 491, 187, 289, 326, 667 |
491, 11, 17, 326, 667 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 491 x 11 x 17 x 326 x 667 = 1018208477814
Therefore, the lowest common multiple of 491,561,867,978,667 is 1018208477814.
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.
491 x 561 x 867 x 978 x 667 = 155785897105542
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.
491 : 1, 491
561 : 1, 3, 11, 17, 33, 51, 187, 561
867 : 1, 3, 17, 51, 289, 867
978 : 1, 2, 3, 6, 163, 326, 489, 978
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,561,867,978,667, is 1.
Now, the common factors can be found like this.
491:491
561:3x 11x 17
867:3x 17x 17
978:2x 3x 163
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 155785897105542/(1x153)
LCM = 155785897105542/153
LCM = 1018208477814
Thus, we can understand that the LCM of 491,561,867,978,667 is 1018208477814.
