Given numbers are 252,980,903,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 252,980,903,947 is 359159220.
Find LCM of 252,980,903,947 with Prime Factorization
| 2 | 252, 980, 903, 947 |
| 2 | 126, 490, 903, 947 |
| 3 | 63, 245, 903, 947 |
| 7 | 21, 245, 301, 947 |
| 3, 35, 43, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 3 x 35 x 43 x 947 = 359159220
Therefore, the lowest common multiple of 252,980,903,947 is 359159220.
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.
252 x 980 x 903 x 947 = 211185621360
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
903 : 1, 3, 7, 21, 43, 129, 301, 903
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,980,903,947, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
980:2x 2x 5x 7x 7
903:3x 7x 43
947:947
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 211185621360/(1x588)
LCM = 211185621360/588
LCM = 359159220
Thus, we can understand that the LCM of 252,980,903,947 is 359159220.
