Given numbers are 671,936,946,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,936,946,815 is 22010222520.
Find LCM of 671,936,946,815 with Prime Factorization
| 2 | 671, 936, 946, 815 |
| 11 | 671, 468, 473, 815 |
| 61, 468, 43, 815 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 61 x 468 x 43 x 815 = 22010222520
Therefore, the lowest common multiple of 671,936,946,815 is 22010222520.
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.
671 x 936 x 946 x 815 = 484224895440
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.
671 : 1, 11, 61, 671
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
946 : 1, 2, 11, 22, 43, 86, 473, 946
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,936,946,815, is 1.
Now, the common factors can be found like this.
671:11x 61
936:2x 2x 2x 3x 3x 13
946:2x 11x 43
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 484224895440/(1x22)
LCM = 484224895440/22
LCM = 22010222520
Thus, we can understand that the LCM of 671,936,946,815 is 22010222520.
