Given numbers are 647,802,966,189,825
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,802,966,189,825 is 620298859950.
Find LCM of 647,802,966,189,825 with Prime Factorization
| 2 | 647, 802, 966, 189, 825 |
| 3 | 647, 401, 483, 189, 825 |
| 7 | 647, 401, 161, 63, 275 |
| 647, 401, 23, 9, 275 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 647 x 401 x 23 x 9 x 275 = 620298859950
Therefore, the lowest common multiple of 647,802,966,189,825 is 620298859950.
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.
647 x 802 x 966 x 189 x 825 = 78157656353700
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.
647 : 1, 647
802 : 1, 2, 401, 802
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
189 : 1, 3, 7, 9, 21, 27, 63, 189
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,802,966,189,825, is 1.
Now, the common factors can be found like this.
647:647
802:2x 401
966:2x 3x 7x 23
189:3x 3x 3x 7
825:3x 5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 78157656353700/(1x126)
LCM = 78157656353700/126
LCM = 620298859950
Thus, we can understand that the LCM of 647,802,966,189,825 is 620298859950.
