Find LCM of 516,645,152,140,655 with Prime Factorization
| 2 | 516, 645, 152, 140, 655 |
| 2 | 258, 645, 76, 70, 655 |
| 3 | 129, 645, 38, 35, 655 |
| 5 | 43, 215, 38, 35, 655 |
| 43 | 43, 43, 38, 7, 131 |
| 1, 1, 38, 7, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 1 x 1 x 38 x 7 x 131 = 89902680
Therefore, the lowest common multiple of 516,645,152,140,655 is 89902680.
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.
516 x 645 x 152 x 140 x 655 = 4638978288000
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
645 : 1, 3, 5, 15, 43, 129, 215, 645
152 : 1, 2, 4, 8, 19, 38, 76, 152
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,645,152,140,655, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
645:3x 5x 43
152:2x 2x 2x 19
140:2x 2x 5x 7
655:5x 131
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 3x 5x 5x 43 = 51600
Therefore, the value for common factors is 51600.
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 = 4638978288000/(1x51600)
LCM = 4638978288000/51600
LCM = 89902680
Thus, we can understand that the LCM of 516,645,152,140,655 is 89902680.
