Given numbers are 638,867,116,803,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,867,116,803,402 is 5410874172.
Find LCM of 638,867,116,803,402 with Prime Factorization
| 2 | 638, 867, 116, 803, 402 |
| 3 | 319, 867, 58, 803, 201 |
| 11 | 319, 289, 58, 803, 67 |
| 29 | 29, 289, 58, 73, 67 |
| 1, 289, 2, 73, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 1 x 289 x 2 x 73 x 67 = 5410874172
Therefore, the lowest common multiple of 638,867,116,803,402 is 5410874172.
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.
638 x 867 x 116 x 803 x 402 = 20712826330416
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
867 : 1, 3, 17, 51, 289, 867
116 : 1, 2, 4, 29, 58, 116
803 : 1, 11, 73, 803
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,867,116,803,402, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
867:3x 17x 17
116:2x 2x 29
803:11x 73
402:2x 3x 67
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 3x 11x 29 = 3828
Therefore, the value for common factors is 3828.
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 = 20712826330416/(1x3828)
LCM = 20712826330416/3828
LCM = 5410874172
Thus, we can understand that the LCM of 638,867,116,803,402 is 5410874172.
