Given numbers are 112,747,869,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 112,747,869,987 is 3417088752.
Find LCM of 112,747,869,987 with Prime Factorization
| 3 | 112, 747, 869, 987 |
| 7 | 112, 249, 869, 329 |
| 16, 249, 869, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 16 x 249 x 869 x 47 = 3417088752
Therefore, the lowest common multiple of 112,747,869,987 is 3417088752.
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.
112 x 747 x 869 x 987 = 71758863792
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.
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
747 : 1, 3, 9, 83, 249, 747
869 : 1, 11, 79, 869
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 112,747,869,987, is 1.
Now, the common factors can be found like this.
112:2x 2x 2x 2x 7
747:3x 3x 83
869:11x 79
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 71758863792/(1x21)
LCM = 71758863792/21
LCM = 3417088752
Thus, we can understand that the LCM of 112,747,869,987 is 3417088752.
