Given numbers are 156,341,561,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,341,561,551 is 498286932.
Find LCM of 156,341,561,551 with Prime Factorization
| 3 | 156, 341, 561, 551 |
| 11 | 52, 341, 187, 551 |
| 52, 31, 17, 551 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 52 x 31 x 17 x 551 = 498286932
Therefore, the lowest common multiple of 156,341,561,551 is 498286932.
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.
156 x 341 x 561 x 551 = 16443468756
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
341 : 1, 11, 31, 341
561 : 1, 3, 11, 17, 33, 51, 187, 561
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,341,561,551, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
341:11x 31
561:3x 11x 17
551:19x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 16443468756/(1x33)
LCM = 16443468756/33
LCM = 498286932
Thus, we can understand that the LCM of 156,341,561,551 is 498286932.
