Find LCM of 780,307,872,759,517 with Prime Factorization
2 | 780, 307, 872, 759, 517 |
2 | 390, 307, 436, 759, 517 |
3 | 195, 307, 218, 759, 517 |
11 | 65, 307, 218, 253, 517 |
65, 307, 218, 23, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 65 x 307 x 218 x 23 x 47 = 620737311480
Therefore, the lowest common multiple of 780,307,872,759,517 is 620737311480.
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.
780 x 307 x 872 x 759 x 517 = 81937325115360
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.
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
307 : 1, 307
872 : 1, 2, 4, 8, 109, 218, 436, 872
759 : 1, 3, 11, 23, 33, 69, 253, 759
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,307,872,759,517, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
307:307
872:2x 2x 2x 109
759:3x 11x 23
517:11x 47
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 11 = 132
Therefore, the value for common factors is 132.
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 = 81937325115360/(1x132)
LCM = 81937325115360/132
LCM = 620737311480
Thus, we can understand that the LCM of 780,307,872,759,517 is 620737311480.
