Given numbers are 669,429,774,131
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,429,774,131 is 3233353266.
Find LCM of 669,429,774,131 with Prime Factorization
| 3 | 669, 429, 774, 131 |
| 223, 143, 258, 131 |
Multiply the prime numbers at the bottom and the left side.
3 x 223 x 143 x 258 x 131 = 3233353266
Therefore, the lowest common multiple of 669,429,774,131 is 3233353266.
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.
669 x 429 x 774 x 131 = 29100179394
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.
669 : 1, 3, 223, 669
429 : 1, 3, 11, 13, 33, 39, 143, 429
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,429,774,131, is 1.
Now, the common factors can be found like this.
669:3x 223
429:3x 11x 13
774:2x 3x 3x 43
131:131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 29100179394/(1x9)
LCM = 29100179394/9
LCM = 3233353266
Thus, we can understand that the LCM of 669,429,774,131 is 3233353266.
