Find LCM of 782,301,787,731,238 with Prime Factorization
| 2 | 782, 301, 787, 731, 238 |
| 7 | 391, 301, 787, 731, 119 |
| 17 | 391, 43, 787, 731, 17 |
| 43 | 23, 43, 787, 43, 1 |
| 23, 1, 787, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 43 x 23 x 1 x 787 x 1 x 1 = 185245634
Therefore, the lowest common multiple of 782,301,787,731,238 is 185245634.
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.
782 x 301 x 787 x 731 x 238 = 32228664912052
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
301 : 1, 7, 43, 301
787 : 1, 787
731 : 1, 17, 43, 731
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,301,787,731,238, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
301:7x 43
787:787
731:17x 43
238:2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 17x 17x 43 = 173978
Therefore, the value for common factors is 173978.
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 = 32228664912052/(1x173978)
LCM = 32228664912052/173978
LCM = 185245634
Thus, we can understand that the LCM of 782,301,787,731,238 is 185245634.
