Given numbers are 881,253,690,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 881,253,690,121 is 73554690.
Find LCM of 881,253,690,121 with Prime Factorization
11 | 881, 253, 690, 121 |
23 | 881, 23, 690, 11 |
881, 1, 30, 11 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 881 x 1 x 30 x 11 = 73554690
Therefore, the lowest common multiple of 881,253,690,121 is 73554690.
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.
881 x 253 x 690 x 121 = 18609336570
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.
881 : 1, 881
253 : 1, 11, 23, 253
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 881,253,690,121, is 1.
Now, the common factors can be found like this.
881:881
253:11x 23
690:2x 3x 5x 23
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23 = 253
Therefore, the value for common factors is 253.
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 = 18609336570/(1x253)
LCM = 18609336570/253
LCM = 73554690
Thus, we can understand that the LCM of 881,253,690,121 is 73554690.
