Find LCM of 780,260,916,455,851 with Prime Factorization
| 2 | 780, 260, 916, 455, 851 |
| 2 | 390, 130, 458, 455, 851 |
| 5 | 195, 65, 229, 455, 851 |
| 13 | 39, 13, 229, 91, 851 |
| 3, 1, 229, 7, 851 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 3 x 1 x 229 x 7 x 851 = 1064039340
Therefore, the lowest common multiple of 780,260,916,455,851 is 1064039340.
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 260 x 916 x 455 x 851 = 71929059384000
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
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
916 : 1, 2, 4, 229, 458, 916
455 : 1, 5, 7, 13, 35, 65, 91, 455
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,260,916,455,851, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
260:2x 2x 5x 13
916:2x 2x 229
455:5x 7x 13
851:23x 37
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 5x 5x 13x 13 = 67600
Therefore, the value for common factors is 67600.
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 = 71929059384000/(1x67600)
LCM = 71929059384000/67600
LCM = 1064039340
Thus, we can understand that the LCM of 780,260,916,455,851 is 1064039340.
