Given numbers are 621,150,985,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,150,985,788 is 12233700.
Find LCM of 621,150,985,788 with Prime Factorization
2 | 621, 150, 985, 788 |
3 | 621, 75, 985, 394 |
5 | 207, 25, 985, 394 |
197 | 207, 5, 197, 394 |
207, 5, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 197 x 207 x 5 x 1 x 2 = 12233700
Therefore, the lowest common multiple of 621,150,985,788 is 12233700.
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.
621 x 150 x 985 x 788 = 72301167000
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
985 : 1, 5, 197, 985
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,150,985,788, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
150:2x 3x 5x 5
985:5x 197
788:2x 2x 197
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 5x 197 = 5910
Therefore, the value for common factors is 5910.
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 = 72301167000/(1x5910)
LCM = 72301167000/5910
LCM = 12233700
Thus, we can understand that the LCM of 621,150,985,788 is 12233700.
