Given numbers are 561,437,936,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,437,936,361 is 1453290696.
Find LCM of 561,437,936,361 with Prime Factorization
| 3 | 561, 437, 936, 361 |
| 19 | 187, 437, 312, 361 |
| 187, 23, 312, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 187 x 23 x 312 x 19 = 1453290696
Therefore, the lowest common multiple of 561,437,936,361 is 1453290696.
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.
561 x 437 x 936 x 361 = 82837569672
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
437 : 1, 19, 23, 437
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,437,936,361, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
437:19x 23
936:2x 2x 2x 3x 3x 13
361:19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 82837569672/(1x57)
LCM = 82837569672/57
LCM = 1453290696
Thus, we can understand that the LCM of 561,437,936,361 is 1453290696.
