Find LCM of 781,295,242,236,355 with Prime Factorization
| 2 | 781, 295, 242, 236, 355 |
| 5 | 781, 295, 121, 118, 355 |
| 11 | 781, 59, 121, 118, 71 |
| 59 | 71, 59, 11, 118, 71 |
| 71 | 71, 1, 11, 2, 71 |
| 1, 1, 11, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 59 x 71 x 1 x 1 x 11 x 2 x 1 = 10137380
Therefore, the lowest common multiple of 781,295,242,236,355 is 10137380.
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 295 x 242 x 236 x 355 = 4671203330200
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
295 : 1, 5, 59, 295
242 : 1, 2, 11, 22, 121, 242
236 : 1, 2, 4, 59, 118, 236
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,295,242,236,355, is 1.
Now, the common factors can be found like this.
781:11x 71
295:5x 59
242:2x 11x 11
236:2x 2x 59
355:5x 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 5x 11x 59x 71 = 460790
Therefore, the value for common factors is 460790.
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 = 4671203330200/(1x460790)
LCM = 4671203330200/460790
LCM = 10137380
Thus, we can understand that the LCM of 781,295,242,236,355 is 10137380.
