Given numbers are 7,138,807,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,138,807,649 is 168645246.
Find LCM of 7,138,807,649 with Prime Factorization
3 | 7, 138, 807, 649 |
7, 46, 269, 649 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 46 x 269 x 649 = 168645246
Therefore, the lowest common multiple of 7,138,807,649 is 168645246.
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.
7 x 138 x 807 x 649 = 505935738
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.
7 : 1, 7
138 : 1, 2, 3, 6, 23, 46, 69, 138
807 : 1, 3, 269, 807
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,138,807,649, is 1.
Now, the common factors can be found like this.
7:7
138:2x 3x 23
807:3x 269
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 505935738/(1x3)
LCM = 505935738/3
LCM = 168645246
Thus, we can understand that the LCM of 7,138,807,649 is 168645246.
