Given numbers are 985,252,885,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,252,885,651 is 453994380.
Find LCM of 985,252,885,651 with Prime Factorization
| 3 | 985, 252, 885, 651 |
| 5 | 985, 84, 295, 217 |
| 7 | 197, 84, 59, 217 |
| 197, 12, 59, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 197 x 12 x 59 x 31 = 453994380
Therefore, the lowest common multiple of 985,252,885,651 is 453994380.
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.
985 x 252 x 885 x 651 = 143008229700
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.
985 : 1, 5, 197, 985
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
885 : 1, 3, 5, 15, 59, 177, 295, 885
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,252,885,651, is 1.
Now, the common factors can be found like this.
985:5x 197
252:2x 2x 3x 3x 7
885:3x 5x 59
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 143008229700/(1x315)
LCM = 143008229700/315
LCM = 453994380
Thus, we can understand that the LCM of 985,252,885,651 is 453994380.
