Find LCM of 831,939,821,780,880 with Prime Factorization
2 | 831, 939, 821, 780, 880 |
2 | 831, 939, 821, 390, 440 |
3 | 831, 939, 821, 195, 220 |
5 | 277, 313, 821, 65, 220 |
277, 313, 821, 13, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 277 x 313 x 821 x 13 x 44 = 2442949800720
Therefore, the lowest common multiple of 831,939,821,780,880 is 2442949800720.
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.
831 x 939 x 821 x 780 x 880 = 439730964129600
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.
831 : 1, 3, 277, 831
939 : 1, 3, 313, 939
821 : 1, 821
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,939,821,780,880, is 1.
Now, the common factors can be found like this.
831:3x 277
939:3x 313
821:821
780:2x 2x 3x 5x 13
880:2x 2x 2x 2x 5x 11
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 439730964129600/(1x180)
LCM = 439730964129600/180
LCM = 2442949800720
Thus, we can understand that the LCM of 831,939,821,780,880 is 2442949800720.
