Find LCM of 780,985,428,359,540 with Prime Factorization
| 2 | 780, 985, 428, 359, 540 |
| 2 | 390, 985, 214, 359, 270 |
| 3 | 195, 985, 107, 359, 135 |
| 5 | 65, 985, 107, 359, 45 |
| 13, 197, 107, 359, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 197 x 107 x 359 x 9 = 53122874220
Therefore, the lowest common multiple of 780,985,428,359,540 is 53122874220.
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 985 x 428 x 359 x 540 = 63747449064000
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
985 : 1, 5, 197, 985
428 : 1, 2, 4, 107, 214, 428
359 : 1, 359
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,985,428,359,540, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
985:5x 197
428:2x 2x 107
359:359
540:2x 2x 3x 3x 3x 5
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 2x 2x 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 63747449064000/(1x1200)
LCM = 63747449064000/1200
LCM = 53122874220
Thus, we can understand that the LCM of 780,985,428,359,540 is 53122874220.
