Given numbers are 139,973,954,661,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,973,954,661,818 is 250949296458.
Find LCM of 139,973,954,661,818 with Prime Factorization
| 2 | 139, 973, 954, 661, 818 |
| 139 | 139, 973, 477, 661, 409 |
| 1, 7, 477, 661, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 1 x 7 x 477 x 661 x 409 = 250949296458
Therefore, the lowest common multiple of 139,973,954,661,818 is 250949296458.
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.
139 x 973 x 954 x 661 x 818 = 69763904415324
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.
139 : 1, 139
973 : 1, 7, 139, 973
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
661 : 1, 661
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,973,954,661,818, is 1.
Now, the common factors can be found like this.
139:139
973:7x 139
954:2x 3x 3x 53
661:661
818:2x 409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 139 = 278
Therefore, the value for common factors is 278.
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 = 69763904415324/(1x278)
LCM = 69763904415324/278
LCM = 250949296458
Thus, we can understand that the LCM of 139,973,954,661,818 is 250949296458.
