Given numbers are 551,957,946,390,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,957,946,390,992 is 50414913120.
Find LCM of 551,957,946,390,992 with Prime Factorization
| 2 | 551, 957, 946, 390, 992 |
| 3 | 551, 957, 473, 195, 496 |
| 11 | 551, 319, 473, 65, 496 |
| 29 | 551, 29, 43, 65, 496 |
| 19, 1, 43, 65, 496 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 19 x 1 x 43 x 65 x 496 = 50414913120
Therefore, the lowest common multiple of 551,957,946,390,992 is 50414913120.
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.
551 x 957 x 946 x 390 x 992 = 192988287423360
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.
551 : 1, 19, 29, 551
957 : 1, 3, 11, 29, 33, 87, 319, 957
946 : 1, 2, 11, 22, 43, 86, 473, 946
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,957,946,390,992, is 1.
Now, the common factors can be found like this.
551:19x 29
957:3x 11x 29
946:2x 11x 43
390:2x 3x 5x 13
992:2x 2x 2x 2x 2x 31
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 11x 29 = 3828
Therefore, the value for common factors is 3828.
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 = 192988287423360/(1x3828)
LCM = 192988287423360/3828
LCM = 50414913120
Thus, we can understand that the LCM of 551,957,946,390,992 is 50414913120.
