Given numbers are 238,781,169,771,273
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,781,169,771,273 is 24219717522.
Find LCM of 238,781,169,771,273 with Prime Factorization
| 3 | 238, 781, 169, 771, 273 |
| 7 | 238, 781, 169, 257, 91 |
| 13 | 34, 781, 169, 257, 13 |
| 34, 781, 1, 257, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 34 x 781 x 1 x 257 x 13 = 24219717522
Therefore, the lowest common multiple of 238,781,169,771,273 is 24219717522.
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 169 x 771 x 273 = 6611982883506
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
169 : 1, 13, 169
771 : 1, 3, 257, 771
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,781,169,771,273, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
781:11x 71
169:13x 13
771:3x 257
273:3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13 = 273
Therefore, the value for common factors is 273.
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 = 6611982883506/(1x273)
LCM = 6611982883506/273
LCM = 24219717522
Thus, we can understand that the LCM of 238,781,169,771,273 is 24219717522.
