Given numbers are 478,154,869,638,111
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,154,869,638,111 is 9359802606.
Find LCM of 478,154,869,638,111 with Prime Factorization
| 2 | 478, 154, 869, 638, 111 |
| 11 | 239, 77, 869, 319, 111 |
| 239, 7, 79, 29, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 239 x 7 x 79 x 29 x 111 = 9359802606
Therefore, the lowest common multiple of 478,154,869,638,111 is 9359802606.
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.
478 x 154 x 869 x 638 x 111 = 4530144461304
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.
478 : 1, 2, 239, 478
154 : 1, 2, 7, 11, 14, 22, 77, 154
869 : 1, 11, 79, 869
638 : 1, 2, 11, 22, 29, 58, 319, 638
111 : 1, 3, 37, 111
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,154,869,638,111, is 1.
Now, the common factors can be found like this.
478:2x 239
154:2x 7x 11
869:11x 79
638:2x 11x 29
111:3x 37
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 4530144461304/(1x484)
LCM = 4530144461304/484
LCM = 9359802606
Thus, we can understand that the LCM of 478,154,869,638,111 is 9359802606.
