Given numbers are 305,671,429,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,671,429,492 is 21458580.
Find LCM of 305,671,429,492 with Prime Factorization
| 3 | 305, 671, 429, 492 |
| 11 | 305, 671, 143, 164 |
| 61 | 305, 61, 13, 164 |
| 5, 1, 13, 164 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 61 x 5 x 1 x 13 x 164 = 21458580
Therefore, the lowest common multiple of 305,671,429,492 is 21458580.
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.
305 x 671 x 429 x 492 = 43196121540
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.
305 : 1, 5, 61, 305
671 : 1, 11, 61, 671
429 : 1, 3, 11, 13, 33, 39, 143, 429
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,671,429,492, is 1.
Now, the common factors can be found like this.
305:5x 61
671:11x 61
429:3x 11x 13
492:2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 61 = 2013
Therefore, the value for common factors is 2013.
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 = 43196121540/(1x2013)
LCM = 43196121540/2013
LCM = 21458580
Thus, we can understand that the LCM of 305,671,429,492 is 21458580.
