Given numbers are 210,987,648,366
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 210,987,648,366 is 65023560.
Find LCM of 210,987,648,366 with Prime Factorization
| 2 | 210, 987, 648, 366 |
| 3 | 105, 987, 324, 183 |
| 7 | 35, 329, 108, 61 |
| 5, 47, 108, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 5 x 47 x 108 x 61 = 65023560
Therefore, the lowest common multiple of 210,987,648,366 is 65023560.
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.
210 x 987 x 648 x 366 = 49157811360
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
987 : 1, 3, 7, 21, 47, 141, 329, 987
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
366 : 1, 2, 3, 6, 61, 122, 183, 366
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,987,648,366, is 3.
Now, the common factors can be found like this.
210:2x 3x 5x 7
987:3x 7x 47
648:2x 2x 2x 3x 3x 3x 3
366:2x 3x 61
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 49157811360/(3x252)
LCM = 49157811360/756
LCM = 65023560
Thus, we can understand that the LCM of 210,987,648,366 is 65023560.
