Given numbers are 311,620,450,845,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,620,450,845,782 is 573360875100.
Find LCM of 311,620,450,845,782 with Prime Factorization
2 | 311, 620, 450, 845, 782 |
5 | 311, 310, 225, 845, 391 |
311, 62, 45, 169, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 311 x 62 x 45 x 169 x 391 = 573360875100
Therefore, the lowest common multiple of 311,620,450,845,782 is 573360875100.
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.
311 x 620 x 450 x 845 x 782 = 57336087510000
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.
311 : 1, 311
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
845 : 1, 5, 13, 65, 169, 845
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,620,450,845,782, is 1.
Now, the common factors can be found like this.
311:311
620:2x 2x 5x 31
450:2x 3x 3x 5x 5
845:5x 13x 13
782:2x 17x 23
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 57336087510000/(1x100)
LCM = 57336087510000/100
LCM = 573360875100
Thus, we can understand that the LCM of 311,620,450,845,782 is 573360875100.
