Find LCM of 630,622,309,686,783 with Prime Factorization
2 | 630, 622, 309, 686, 783 |
3 | 315, 311, 309, 343, 783 |
3 | 105, 311, 103, 343, 261 |
7 | 35, 311, 103, 343, 87 |
5, 311, 103, 49, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 5 x 311 x 103 x 49 x 87 = 86030707770
Therefore, the lowest common multiple of 630,622,309,686,783 is 86030707770.
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.
630 x 622 x 309 x 686 x 783 = 65039215074120
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
622 : 1, 2, 311, 622
309 : 1, 3, 103, 309
686 : 1, 2, 7, 14, 49, 98, 343, 686
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,622,309,686,783, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
622:2x 311
309:3x 103
686:2x 7x 7x 7
783:3x 3x 3x 29
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 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 65039215074120/(1x756)
LCM = 65039215074120/756
LCM = 86030707770
Thus, we can understand that the LCM of 630,622,309,686,783 is 86030707770.
