Given numbers are 784,172,998,847,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,172,998,847,554 is 563832626896.
Find LCM of 784,172,998,847,554 with Prime Factorization
| 2 | 784, 172, 998, 847, 554 |
| 2 | 392, 86, 499, 847, 277 |
| 7 | 196, 43, 499, 847, 277 |
| 28, 43, 499, 121, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 28 x 43 x 499 x 121 x 277 = 563832626896
Therefore, the lowest common multiple of 784,172,998,847,554 is 563832626896.
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.
784 x 172 x 998 x 847 x 554 = 63149254212352
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
172 : 1, 2, 4, 43, 86, 172
998 : 1, 2, 499, 998
847 : 1, 7, 11, 77, 121, 847
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,172,998,847,554, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
172:2x 2x 43
998:2x 499
847:7x 11x 11
554:2x 277
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 = 63149254212352/(1x112)
LCM = 63149254212352/112
LCM = 563832626896
Thus, we can understand that the LCM of 784,172,998,847,554 is 563832626896.
