Given numbers are 650,783,845,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 650,783,845,821 is 5432023350.
Find LCM of 650,783,845,821 with Prime Factorization
5 | 650, 783, 845, 821 |
13 | 130, 783, 169, 821 |
10, 783, 13, 821 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 10 x 783 x 13 x 821 = 5432023350
Therefore, the lowest common multiple of 650,783,845,821 is 5432023350.
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.
650 x 783 x 845 x 821 = 353081517750
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.
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
783 : 1, 3, 9, 27, 29, 87, 261, 783
845 : 1, 5, 13, 65, 169, 845
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,783,845,821, is 1.
Now, the common factors can be found like this.
650:2x 5x 5x 13
783:3x 3x 3x 29
845:5x 13x 13
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13 = 65
Therefore, the value for common factors is 65.
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 = 353081517750/(1x65)
LCM = 353081517750/65
LCM = 5432023350
Thus, we can understand that the LCM of 650,783,845,821 is 5432023350.
