Given numbers are 796,508,420,896
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 796,508,420,896 is 339669120.
Find LCM of 796,508,420,896 with Prime Factorization
| 2 | 796, 508, 420, 896 |
| 2 | 398, 254, 210, 448 |
| 7 | 199, 127, 105, 224 |
| 199, 127, 15, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 199 x 127 x 15 x 32 = 339669120
Therefore, the lowest common multiple of 796,508,420,896 is 339669120.
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.
796 x 508 x 420 x 896 = 152171765760
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.
796 : 1, 2, 4, 199, 398, 796
508 : 1, 2, 4, 127, 254, 508
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
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 796,508,420,896, is 4.
Now, the common factors can be found like this.
796:2x 2x 199
508:2x 2x 127
420:2x 2x 3x 5x 7
896:2x 2x 2x 2x 2x 2x 2x 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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 152171765760/(4x112)
LCM = 152171765760/448
LCM = 339669120
Thus, we can understand that the LCM of 796,508,420,896 is 339669120.
