Find LCM of 125,726,234,781,639 with Prime Factorization
| 2 | 125, 726, 234, 781, 639 |
| 3 | 125, 363, 117, 781, 639 |
| 3 | 125, 121, 39, 781, 213 |
| 11 | 125, 121, 13, 781, 71 |
| 71 | 125, 11, 13, 71, 71 |
| 125, 11, 13, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 71 x 125 x 11 x 13 x 1 x 1 = 251286750
Therefore, the lowest common multiple of 125,726,234,781,639 is 251286750.
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.
125 x 726 x 234 x 781 x 639 = 10597767394500
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.
125 : 1, 5, 25, 125
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
781 : 1, 11, 71, 781
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 125,726,234,781,639, is 1.
Now, the common factors can be found like this.
125:5x 5x 5
726:2x 3x 11x 11
234:2x 3x 3x 13
781:11x 71
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 11x 71 = 42174
Therefore, the value for common factors is 42174.
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 = 10597767394500/(1x42174)
LCM = 10597767394500/42174
LCM = 251286750
Thus, we can understand that the LCM of 125,726,234,781,639 is 251286750.
