Given numbers are 235,557,724,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 235,557,724,840 is 3980255160.
Find LCM of 235,557,724,840 with Prime Factorization
| 2 | 235, 557, 724, 840 |
| 2 | 235, 557, 362, 420 |
| 5 | 235, 557, 181, 210 |
| 47, 557, 181, 42 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 47 x 557 x 181 x 42 = 3980255160
Therefore, the lowest common multiple of 235,557,724,840 is 3980255160.
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.
235 x 557 x 724 x 840 = 79605103200
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.
235 : 1, 5, 47, 235
557 : 1, 557
724 : 1, 2, 4, 181, 362, 724
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 235,557,724,840, is 1.
Now, the common factors can be found like this.
235:5x 47
557:557
724:2x 2x 181
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 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 79605103200/(1x20)
LCM = 79605103200/20
LCM = 3980255160
Thus, we can understand that the LCM of 235,557,724,840 is 3980255160.
