Given numbers are 836,238,402,280,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,238,402,280,794 is 79385247480.
Find LCM of 836,238,402,280,794 with Prime Factorization
| 2 | 836, 238, 402, 280, 794 |
| 2 | 418, 119, 201, 140, 397 |
| 7 | 209, 119, 201, 70, 397 |
| 209, 17, 201, 10, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 209 x 17 x 201 x 10 x 397 = 79385247480
Therefore, the lowest common multiple of 836,238,402,280,794 is 79385247480.
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.
836 x 238 x 402 x 280 x 794 = 17782295435520
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
238 : 1, 2, 7, 14, 17, 34, 119, 238
402 : 1, 2, 3, 6, 67, 134, 201, 402
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
794 : 1, 2, 397, 794
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,238,402,280,794, is 2.
Now, the common factors can be found like this.
836:2x 2x 11x 19
238:2x 7x 17
402:2x 3x 67
280:2x 2x 2x 5x 7
794:2x 397
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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 17782295435520/(2x112)
LCM = 17782295435520/224
LCM = 79385247480
Thus, we can understand that the LCM of 836,238,402,280,794 is 79385247480.
