Find LCM of 765,809,519,836,420 with Prime Factorization
2 | 765, 809, 519, 836, 420 |
2 | 765, 809, 519, 418, 210 |
3 | 765, 809, 519, 209, 105 |
5 | 255, 809, 173, 209, 35 |
51, 809, 173, 209, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 51 x 809 x 173 x 209 x 7 = 626556698460
Therefore, the lowest common multiple of 765,809,519,836,420 is 626556698460.
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.
765 x 809 x 519 x 836 x 420 = 112780205722800
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
809 : 1, 809
519 : 1, 3, 173, 519
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,809,519,836,420, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
809:809
519:3x 173
836:2x 2x 11x 19
420:2x 2x 3x 5x 7
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 = 112780205722800/(1x180)
LCM = 112780205722800/180
LCM = 626556698460
Thus, we can understand that the LCM of 765,809,519,836,420 is 626556698460.
