Find LCM of 655,520,689,956,775 with Prime Factorization
| 2 | 655, 520, 689, 956, 775 |
| 2 | 655, 260, 689, 478, 775 |
| 5 | 655, 130, 689, 239, 775 |
| 13 | 131, 26, 689, 239, 155 |
| 131, 2, 53, 239, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 131 x 2 x 53 x 239 x 155 = 133745786200
Therefore, the lowest common multiple of 655,520,689,956,775 is 133745786200.
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.
655 x 520 x 689 x 956 x 775 = 173869522060000
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.
655 : 1, 5, 131, 655
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
689 : 1, 13, 53, 689
956 : 1, 2, 4, 239, 478, 956
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,520,689,956,775, is 1.
Now, the common factors can be found like this.
655:5x 131
520:2x 2x 2x 5x 13
689:13x 53
956:2x 2x 239
775:5x 5x 31
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 5x 5x 13 = 1300
Therefore, the value for common factors is 1300.
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 = 173869522060000/(1x1300)
LCM = 173869522060000/1300
LCM = 133745786200
Thus, we can understand that the LCM of 655,520,689,956,775 is 133745786200.
