Find LCM of 782,986,880,480 with Prime Factorization
| 2 | 782, 986, 880, 480 |
| 2 | 391, 493, 440, 240 |
| 2 | 391, 493, 220, 120 |
| 2 | 391, 493, 110, 60 |
| 5 | 391, 493, 55, 30 |
| 17 | 391, 493, 11, 6 |
| 23, 29, 11, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 17 x 23 x 29 x 11 x 6 = 59869920
Therefore, the lowest common multiple of 782,986,880,480 is 59869920.
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.
782 x 986 x 880 x 480 = 325692364800
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
986 : 1, 2, 17, 29, 34, 58, 493, 986
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,986,880,480, is 2.
Now, the common factors can be found like this.
782:2x 17x 23
986:2x 17x 29
880:2x 2x 2x 2x 5x 11
480:2x 2x 2x 2x 2x 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 2x 5x 17 = 2720
Therefore, the value for common factors is 2720.
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 = 325692364800/(2x2720)
LCM = 325692364800/5440
LCM = 59869920
Thus, we can understand that the LCM of 782,986,880,480 is 59869920.
