Given numbers are 138,527,878,302,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,527,878,302,661 is 3186637251054.
Find LCM of 138,527,878,302,661 with Prime Factorization
| 2 | 138, 527, 878, 302, 661 |
| 69, 527, 439, 151, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 69 x 527 x 439 x 151 x 661 = 3186637251054
Therefore, the lowest common multiple of 138,527,878,302,661 is 3186637251054.
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.
138 x 527 x 878 x 302 x 661 = 12746549004216
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
527 : 1, 17, 31, 527
878 : 1, 2, 439, 878
302 : 1, 2, 151, 302
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,527,878,302,661, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
527:17x 31
878:2x 439
302:2x 151
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 12746549004216/(1x4)
LCM = 12746549004216/4
LCM = 3186637251054
Thus, we can understand that the LCM of 138,527,878,302,661 is 3186637251054.
