Find LCM of 749,686,390,871,606 with Prime Factorization
| 2 | 749, 686, 390, 871, 606 |
| 3 | 749, 343, 195, 871, 303 |
| 7 | 749, 343, 65, 871, 101 |
| 13 | 107, 49, 65, 871, 101 |
| 107, 49, 5, 67, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 107 x 49 x 5 x 67 x 101 = 96858710130
Therefore, the lowest common multiple of 749,686,390,871,606 is 96858710130.
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.
749 x 686 x 390 x 871 x 606 = 105769711461960
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.
749 : 1, 7, 107, 749
686 : 1, 2, 7, 14, 49, 98, 343, 686
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
871 : 1, 13, 67, 871
606 : 1, 2, 3, 6, 101, 202, 303, 606
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,686,390,871,606, is 1.
Now, the common factors can be found like this.
749:7x 107
686:2x 7x 7x 7
390:2x 3x 5x 13
871:13x 67
606:2x 3x 101
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 3x 7x 13 = 1092
Therefore, the value for common factors is 1092.
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 = 105769711461960/(1x1092)
LCM = 105769711461960/1092
LCM = 96858710130
Thus, we can understand that the LCM of 749,686,390,871,606 is 96858710130.
