Given numbers are 236,743,649,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 236,743,649,840 is 405053880.
Find LCM of 236,743,649,840 with Prime Factorization
| 2 | 236, 743, 649, 840 |
| 2 | 118, 743, 649, 420 |
| 59 | 59, 743, 649, 210 |
| 1, 743, 11, 210 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 59 x 1 x 743 x 11 x 210 = 405053880
Therefore, the lowest common multiple of 236,743,649,840 is 405053880.
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.
236 x 743 x 649 x 840 = 95592715680
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.
236 : 1, 2, 4, 59, 118, 236
743 : 1, 743
649 : 1, 11, 59, 649
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 236,743,649,840, is 1.
Now, the common factors can be found like this.
236:2x 2x 59
743:743
649:11x 59
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 59 = 236
Therefore, the value for common factors is 236.
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 = 95592715680/(1x236)
LCM = 95592715680/236
LCM = 405053880
Thus, we can understand that the LCM of 236,743,649,840 is 405053880.
