Given numbers are 143,839,154,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,839,154,781 is 119257138.
Find LCM of 143,839,154,781 with Prime Factorization
11 | 143, 839, 154, 781 |
13, 839, 14, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 839 x 14 x 71 = 119257138
Therefore, the lowest common multiple of 143,839,154,781 is 119257138.
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.
143 x 839 x 154 x 781 = 14430113698
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.
143 : 1, 11, 13, 143
839 : 1, 839
154 : 1, 2, 7, 11, 14, 22, 77, 154
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,839,154,781, is 1.
Now, the common factors can be found like this.
143:11x 13
839:839
154:2x 7x 11
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 14430113698/(1x121)
LCM = 14430113698/121
LCM = 119257138
Thus, we can understand that the LCM of 143,839,154,781 is 119257138.
