Given numbers are 957,902,611,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,902,611,423 is 143842842.
Find LCM of 957,902,611,423 with Prime Factorization
| 3 | 957, 902, 611, 423 |
| 11 | 319, 902, 611, 141 |
| 47 | 29, 82, 611, 141 |
| 29, 82, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 47 x 29 x 82 x 13 x 3 = 143842842
Therefore, the lowest common multiple of 957,902,611,423 is 143842842.
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.
957 x 902 x 611 x 423 = 223100247942
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
902 : 1, 2, 11, 22, 41, 82, 451, 902
611 : 1, 13, 47, 611
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,902,611,423, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
902:2x 11x 41
611:13x 47
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 47 = 1551
Therefore, the value for common factors is 1551.
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 = 223100247942/(1x1551)
LCM = 223100247942/1551
LCM = 143842842
Thus, we can understand that the LCM of 957,902,611,423 is 143842842.
