Find LCM of 308,506,622,220,645 with Prime Factorization
2 | 308, 506, 622, 220, 645 |
2 | 154, 253, 311, 110, 645 |
5 | 77, 253, 311, 55, 645 |
11 | 77, 253, 311, 11, 129 |
7, 23, 311, 1, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 7 x 23 x 311 x 1 x 129 = 1421014980
Therefore, the lowest common multiple of 308,506,622,220,645 is 1421014980.
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.
308 x 506 x 622 x 220 x 645 = 13755425006400
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
506 : 1, 2, 11, 22, 23, 46, 253, 506
622 : 1, 2, 311, 622
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,506,622,220,645, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
506:2x 11x 23
622:2x 311
220:2x 2x 5x 11
645:3x 5x 43
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 5x 11x 11 = 9680
Therefore, the value for common factors is 9680.
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 = 13755425006400/(1x9680)
LCM = 13755425006400/9680
LCM = 1421014980
Thus, we can understand that the LCM of 308,506,622,220,645 is 1421014980.
