Given numbers are 882,942,998,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 882,942,998,821 is 56729889846.
Find LCM of 882,942,998,821 with Prime Factorization
| 2 | 882, 942, 998, 821 |
| 3 | 441, 471, 499, 821 |
| 147, 157, 499, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 147 x 157 x 499 x 821 = 56729889846
Therefore, the lowest common multiple of 882,942,998,821 is 56729889846.
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.
882 x 942 x 998 x 821 = 680758678152
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
942 : 1, 2, 3, 6, 157, 314, 471, 942
998 : 1, 2, 499, 998
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,942,998,821, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
942:2x 3x 157
998:2x 499
821:821
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 3 = 12
Therefore, the value for common factors is 12.
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 = 680758678152/(1x12)
LCM = 680758678152/12
LCM = 56729889846
Thus, we can understand that the LCM of 882,942,998,821 is 56729889846.
