Given numbers are 231,779,620,476,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,779,620,476,942 is 297776006220.
Find LCM of 231,779,620,476,942 with Prime Factorization
| 2 | 231, 779, 620, 476, 942 |
| 2 | 231, 779, 310, 238, 471 |
| 3 | 231, 779, 155, 119, 471 |
| 7 | 77, 779, 155, 119, 157 |
| 11, 779, 155, 17, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 779 x 155 x 17 x 157 = 297776006220
Therefore, the lowest common multiple of 231,779,620,476,942 is 297776006220.
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.
231 x 779 x 620 x 476 x 942 = 50026369044960
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
779 : 1, 19, 41, 779
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,779,620,476,942, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
779:19x 41
620:2x 2x 5x 31
476:2x 2x 7x 17
942:2x 3x 157
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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 50026369044960/(1x168)
LCM = 50026369044960/168
LCM = 297776006220
Thus, we can understand that the LCM of 231,779,620,476,942 is 297776006220.
