Given numbers are 238,781,935,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,781,935,702 is 326215890.
Find LCM of 238,781,935,702 with Prime Factorization
| 2 | 238, 781, 935, 702 |
| 11 | 119, 781, 935, 351 |
| 17 | 119, 71, 85, 351 |
| 7, 71, 5, 351 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 7 x 71 x 5 x 351 = 326215890
Therefore, the lowest common multiple of 238,781,935,702 is 326215890.
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.
238 x 781 x 935 x 702 = 122004742860
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
781 : 1, 11, 71, 781
935 : 1, 5, 11, 17, 55, 85, 187, 935
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,781,935,702, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
781:11x 71
935:5x 11x 17
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 122004742860/(1x374)
LCM = 122004742860/374
LCM = 326215890
Thus, we can understand that the LCM of 238,781,935,702 is 326215890.
