The LCM of 818,471,749,546,129 is 161312431098.
Find LCM of 818,471,749,546,129 with Prime Factorization
2 | 818, 471, 749, 546, 129 |
3 | 409, 471, 749, 273, 129 |
7 | 409, 157, 749, 91, 43 |
409, 157, 107, 13, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 409 x 157 x 107 x 13 x 43 = 161312431098
Therefore, the lowest common multiple of 818,471,749,546,129 is 161312431098.
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.
818 x 471 x 749 x 546 x 129 = 20325366318348
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.
818 : 1, 2, 409, 818
471 : 1, 3, 157, 471
749 : 1, 7, 107, 749
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,471,749,546,129, is 1.
Now, the common factors can be found like this.
818:2x 409
471:3x 157
749:7x 107
546:2x 3x 7x 13
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 20325366318348/(1x126)
LCM = 20325366318348/126
LCM = 161312431098
Thus, we can understand that the LCM of 818,471,749,546,129 is 161312431098.
