Given numbers are 177,286,646,478,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,286,646,478,455 is 136775328690.
Find LCM of 177,286,646,478,455 with Prime Factorization
2 | 177, 286, 646, 478, 455 |
13 | 177, 143, 323, 239, 455 |
177, 11, 323, 239, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 177 x 11 x 323 x 239 x 35 = 136775328690
Therefore, the lowest common multiple of 177,286,646,478,455 is 136775328690.
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.
177 x 286 x 646 x 478 x 455 = 7112317091880
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.
177 : 1, 3, 59, 177
286 : 1, 2, 11, 13, 22, 26, 143, 286
646 : 1, 2, 17, 19, 34, 38, 323, 646
478 : 1, 2, 239, 478
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,286,646,478,455, is 1.
Now, the common factors can be found like this.
177:3x 59
286:2x 11x 13
646:2x 17x 19
478:2x 239
455:5x 7x 13
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 13 = 52
Therefore, the value for common factors is 52.
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 = 7112317091880/(1x52)
LCM = 7112317091880/52
LCM = 136775328690
Thus, we can understand that the LCM of 177,286,646,478,455 is 136775328690.
