Given numbers are 874,836,478,655,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,836,478,655,388 is 291974584220.
Find LCM of 874,836,478,655,388 with Prime Factorization
| 2 | 874, 836, 478, 655, 388 |
| 2 | 437, 418, 239, 655, 194 |
| 19 | 437, 209, 239, 655, 97 |
| 23, 11, 239, 655, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 23 x 11 x 239 x 655 x 97 = 291974584220
Therefore, the lowest common multiple of 874,836,478,655,388 is 291974584220.
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.
874 x 836 x 478 x 655 x 388 = 88760273602880
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
478 : 1, 2, 239, 478
655 : 1, 5, 131, 655
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,836,478,655,388, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
836:2x 2x 11x 19
478:2x 239
655:5x 131
388:2x 2x 97
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 19 = 304
Therefore, the value for common factors is 304.
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 = 88760273602880/(1x304)
LCM = 88760273602880/304
LCM = 291974584220
Thus, we can understand that the LCM of 874,836,478,655,388 is 291974584220.
