Find LCM of 272,748,781,981,155 with Prime Factorization
| 2 | 272, 748, 781, 981, 155 |
| 2 | 136, 374, 781, 981, 155 |
| 11 | 68, 187, 781, 981, 155 |
| 17 | 68, 17, 71, 981, 155 |
| 4, 1, 71, 981, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 4 x 1 x 71 x 981 x 155 = 32301347760
Therefore, the lowest common multiple of 272,748,781,981,155 is 32301347760.
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.
272 x 748 x 781 x 981 x 155 = 24161408124480
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
781 : 1, 11, 71, 781
981 : 1, 3, 9, 109, 327, 981
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,748,781,981,155, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
748:2x 2x 11x 17
781:11x 71
981:3x 3x 109
155:5x 31
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 24161408124480/(1x748)
LCM = 24161408124480/748
LCM = 32301347760
Thus, we can understand that the LCM of 272,748,781,981,155 is 32301347760.
