The LCM of 588,715,120,865 is 145465320.
Find LCM of 588,715,120,865 with Prime Factorization
| 2 | 588, 715, 120, 865 |
| 2 | 294, 715, 60, 865 |
| 3 | 147, 715, 30, 865 |
| 5 | 49, 715, 10, 865 |
| 49, 143, 2, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 49 x 143 x 2 x 173 = 145465320
Therefore, the lowest common multiple of 588,715,120,865 is 145465320.
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.
588 x 715 x 120 x 865 = 43639596000
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.
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
715 : 1, 5, 11, 13, 55, 65, 143, 715
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 588,715,120,865, is 1.
Now, the common factors can be found like this.
588:2x 2x 3x 7x 7
715:5x 11x 13
120:2x 2x 2x 3x 5
865:5x 173
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 43639596000/(1x300)
LCM = 43639596000/300
LCM = 145465320
Thus, we can understand that the LCM of 588,715,120,865 is 145465320.
