Given numbers are 619,845,455,305,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,845,455,305,425 is 18984281225.
Find LCM of 619,845,455,305,425 with Prime Factorization
| 5 | 619, 845, 455, 305, 425 |
| 13 | 619, 169, 91, 61, 85 |
| 619, 13, 7, 61, 85 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 619 x 13 x 7 x 61 x 85 = 18984281225
Therefore, the lowest common multiple of 619,845,455,305,425 is 18984281225.
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.
619 x 845 x 455 x 305 x 425 = 30849456990625
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.
619 : 1, 619
845 : 1, 5, 13, 65, 169, 845
455 : 1, 5, 7, 13, 35, 65, 91, 455
305 : 1, 5, 61, 305
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,845,455,305,425, is 1.
Now, the common factors can be found like this.
619:619
845:5x 13x 13
455:5x 7x 13
305:5x 61
425:5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5x 13 = 1625
Therefore, the value for common factors is 1625.
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 = 30849456990625/(1x1625)
LCM = 30849456990625/1625
LCM = 18984281225
Thus, we can understand that the LCM of 619,845,455,305,425 is 18984281225.
