Given numbers are 138,613,931,840,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,613,931,840,762 is 200042815560.
Find LCM of 138,613,931,840,762 with Prime Factorization
| 2 | 138, 613, 931, 840, 762 |
| 3 | 69, 613, 931, 420, 381 |
| 7 | 23, 613, 931, 140, 127 |
| 23, 613, 133, 20, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 613 x 133 x 20 x 127 = 200042815560
Therefore, the lowest common multiple of 138,613,931,840,762 is 200042815560.
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 613 x 931 x 840 x 762 = 50410789521120
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
613 : 1, 613
931 : 1, 7, 19, 49, 133, 931
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,613,931,840,762, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
613:613
931:7x 7x 19
840:2x 2x 2x 3x 5x 7
762:2x 3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 50410789521120/(1x252)
LCM = 50410789521120/252
LCM = 200042815560
Thus, we can understand that the LCM of 138,613,931,840,762 is 200042815560.
