Given numbers are 987,803,219,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,803,219,777 is 29324757.
Find LCM of 987,803,219,777 with Prime Factorization
| 3 | 987, 803, 219, 777 |
| 7 | 329, 803, 73, 259 |
| 73 | 47, 803, 73, 37 |
| 47, 11, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 73 x 47 x 11 x 1 x 37 = 29324757
Therefore, the lowest common multiple of 987,803,219,777 is 29324757.
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 803 x 219 x 777 = 134864557443
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
803 : 1, 11, 73, 803
219 : 1, 3, 73, 219
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,803,219,777, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
803:11x 73
219:3x 73
777:3x 7x 37
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 7x 73 = 4599
Therefore, the value for common factors is 4599.
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 = 134864557443/(1x4599)
LCM = 134864557443/4599
LCM = 29324757
Thus, we can understand that the LCM of 987,803,219,777 is 29324757.
