The LCM of 781,492,236,981,344 is 637550149896.
Find LCM of 781,492,236,981,344 with Prime Factorization
| 2 | 781, 492, 236, 981, 344 |
| 2 | 781, 246, 118, 981, 172 |
| 3 | 781, 123, 59, 981, 86 |
| 781, 41, 59, 327, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 781 x 41 x 59 x 327 x 86 = 637550149896
Therefore, the lowest common multiple of 781,492,236,981,344 is 637550149896.
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.
781 x 492 x 236 x 981 x 344 = 30602407195008
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.
781 : 1, 11, 71, 781
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
236 : 1, 2, 4, 59, 118, 236
981 : 1, 3, 9, 109, 327, 981
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,492,236,981,344, is 1.
Now, the common factors can be found like this.
781:11x 71
492:2x 2x 3x 41
236:2x 2x 59
981:3x 3x 109
344:2x 2x 2x 43
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 30602407195008/(1x48)
LCM = 30602407195008/48
LCM = 637550149896
Thus, we can understand that the LCM of 781,492,236,981,344 is 637550149896.
