Given numbers are 438,403,523,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,403,523,169 is 1200118686.
Find LCM of 438,403,523,169 with Prime Factorization
13 | 438, 403, 523, 169 |
438, 31, 523, 13 |
Multiply the prime numbers at the bottom and the left side.
13 x 438 x 31 x 523 x 13 = 1200118686
Therefore, the lowest common multiple of 438,403,523,169 is 1200118686.
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.
438 x 403 x 523 x 169 = 15601542918
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
403 : 1, 13, 31, 403
523 : 1, 523
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,403,523,169, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
403:13x 31
523:523
169:13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 15601542918/(1x13)
LCM = 15601542918/13
LCM = 1200118686
Thus, we can understand that the LCM of 438,403,523,169 is 1200118686.
