Given numbers are 936,561,462,894,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 936,561,462,894,639 is 12961644696.
Find LCM of 936,561,462,894,639 with Prime Factorization
| 2 | 936, 561, 462, 894, 639 |
| 3 | 468, 561, 231, 447, 639 |
| 3 | 156, 187, 77, 149, 213 |
| 11 | 52, 187, 77, 149, 71 |
| 52, 17, 7, 149, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 52 x 17 x 7 x 149 x 71 = 12961644696
Therefore, the lowest common multiple of 936,561,462,894,639 is 12961644696.
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.
936 x 561 x 462 x 894 x 639 = 138585905089632
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.
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
894 : 1, 2, 3, 6, 149, 298, 447, 894
639 : 1, 3, 9, 71, 213, 639
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,561,462,894,639, is 3.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
561:3x 11x 17
462:2x 3x 7x 11
894:2x 3x 149
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 11 = 3564
Therefore, the value for common factors is 3564.
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 = 138585905089632/(3x3564)
LCM = 138585905089632/10692
LCM = 12961644696
Thus, we can understand that the LCM of 936,561,462,894,639 is 12961644696.
