Given numbers are 987,783,373,504
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,783,373,504 is 768699288.
Find LCM of 987,783,373,504 with Prime Factorization
3 | 987, 783, 373, 504 |
3 | 329, 261, 373, 168 |
7 | 329, 87, 373, 56 |
47, 87, 373, 8 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 47 x 87 x 373 x 8 = 768699288
Therefore, the lowest common multiple of 987,783,373,504 is 768699288.
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.
987 x 783 x 373 x 504 = 145284165432
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
783 : 1, 3, 9, 27, 29, 87, 261, 783
373 : 1, 373
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,783,373,504, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
783:3x 3x 3x 29
373:373
504:2x 2x 2x 3x 3x 7
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 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 145284165432/(1x189)
LCM = 145284165432/189
LCM = 768699288
Thus, we can understand that the LCM of 987,783,373,504 is 768699288.
