Find LCM of 682,520,690,160,642 with Prime Factorization
| 2 | 682, 520, 690, 160, 642 |
| 2 | 341, 260, 345, 80, 321 |
| 2 | 341, 130, 345, 40, 321 |
| 3 | 341, 65, 345, 20, 321 |
| 5 | 341, 65, 115, 20, 107 |
| 341, 13, 23, 4, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 341 x 13 x 23 x 4 x 107 = 5236614240
Therefore, the lowest common multiple of 682,520,690,160,642 is 5236614240.
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.
682 x 520 x 690 x 160 x 642 = 25135748352000
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,520,690,160,642, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
520:2x 2x 2x 5x 13
690:2x 3x 5x 23
160:2x 2x 2x 2x 2x 5
642:2x 3x 107
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 2x 2x 2x 3x 5x 5 = 2400
Therefore, the value for common factors is 2400.
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 = 25135748352000/(2x2400)
LCM = 25135748352000/4800
LCM = 5236614240
Thus, we can understand that the LCM of 682,520,690,160,642 is 5236614240.
