Find LCM of 234,238,781,781,518 with Prime Factorization
| 2 | 234, 238, 781, 781, 518 |
| 7 | 117, 119, 781, 781, 259 |
| 11 | 117, 17, 781, 781, 37 |
| 71 | 117, 17, 71, 71, 37 |
| 117, 17, 1, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 71 x 117 x 17 x 1 x 1 x 37 = 804665862
Therefore, the lowest common multiple of 234,238,781,781,518 is 804665862.
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.
234 x 238 x 781 x 781 x 518 = 17596433070216
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.
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
238 : 1, 2, 7, 14, 17, 34, 119, 238
781 : 1, 11, 71, 781
781 : 1, 11, 71, 781
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,238,781,781,518, is 1.
Now, the common factors can be found like this.
234:2x 3x 3x 13
238:2x 7x 17
781:11x 71
781:11x 71
518:2x 7x 37
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 7x 11x 71 = 21868
Therefore, the value for common factors is 21868.
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 = 17596433070216/(1x21868)
LCM = 17596433070216/21868
LCM = 804665862
Thus, we can understand that the LCM of 234,238,781,781,518 is 804665862.
