Given numbers are 125,505,774,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 125,505,774,840 is 273609000.
Find LCM of 125,505,774,840 with Prime Factorization
| 2 | 125, 505, 774, 840 |
| 3 | 125, 505, 387, 420 |
| 5 | 125, 505, 129, 140 |
| 25, 101, 129, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 25 x 101 x 129 x 28 = 273609000
Therefore, the lowest common multiple of 125,505,774,840 is 273609000.
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.
125 x 505 x 774 x 840 = 41041350000
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.
125 : 1, 5, 25, 125
505 : 1, 5, 101, 505
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 125,505,774,840, is 1.
Now, the common factors can be found like this.
125:5x 5x 5
505:5x 101
774:2x 3x 3x 43
840:2x 2x 2x 3x 5x 7
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 5 = 150
Therefore, the value for common factors is 150.
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 = 41041350000/(1x150)
LCM = 41041350000/150
LCM = 273609000
Thus, we can understand that the LCM of 125,505,774,840 is 273609000.
