Find LCM of 791,242,130,605,781 with Prime Factorization
| 2 | 791, 242, 130, 605, 781 |
| 5 | 791, 121, 65, 605, 781 |
| 11 | 791, 121, 13, 121, 781 |
| 11 | 791, 11, 13, 11, 71 |
| 791, 1, 13, 1, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 11 x 791 x 1 x 13 x 1 x 71 = 883412530
Therefore, the lowest common multiple of 791,242,130,605,781 is 883412530.
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.
791 x 242 x 130 x 605 x 781 = 11758220774300
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.
791 : 1, 7, 113, 791
242 : 1, 2, 11, 22, 121, 242
130 : 1, 2, 5, 10, 13, 26, 65, 130
605 : 1, 5, 11, 55, 121, 605
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,242,130,605,781, is 1.
Now, the common factors can be found like this.
791:7x 113
242:2x 11x 11
130:2x 5x 13
605:5x 11x 11
781:11x 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 11x 11 = 13310
Therefore, the value for common factors is 13310.
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 = 11758220774300/(1x13310)
LCM = 11758220774300/13310
LCM = 883412530
Thus, we can understand that the LCM of 791,242,130,605,781 is 883412530.
