Given numbers are 123,820,755,250
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,820,755,250 is 9286500.
Find LCM of 123,820,755,250 with Prime Factorization
2 | 123, 820, 755, 250 |
5 | 123, 410, 755, 125 |
41 | 123, 82, 151, 25 |
3, 2, 151, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 3 x 2 x 151 x 25 = 9286500
Therefore, the lowest common multiple of 123,820,755,250 is 9286500.
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.
123 x 820 x 755 x 250 = 19037325000
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.
123 : 1, 3, 41, 123
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
755 : 1, 5, 151, 755
250 : 1, 2, 5, 10, 25, 50, 125, 250
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,820,755,250, is 1.
Now, the common factors can be found like this.
123:3x 41
820:2x 2x 5x 41
755:5x 151
250:2x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 41 = 2050
Therefore, the value for common factors is 2050.
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 = 19037325000/(1x2050)
LCM = 19037325000/2050
LCM = 9286500
Thus, we can understand that the LCM of 123,820,755,250 is 9286500.
