Find LCM of 630,556,812,649,295 with Prime Factorization
| 2 | 630, 556, 812, 649, 295 |
| 2 | 315, 278, 406, 649, 295 |
| 5 | 315, 139, 203, 649, 295 |
| 7 | 63, 139, 203, 649, 59 |
| 59 | 9, 139, 29, 649, 59 |
| 9, 139, 29, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 59 x 9 x 139 x 29 x 11 x 1 = 3296309940
Therefore, the lowest common multiple of 630,556,812,649,295 is 3296309940.
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 556 x 812 x 649 x 295 = 54455040208800
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
556 : 1, 2, 4, 139, 278, 556
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
649 : 1, 11, 59, 649
295 : 1, 5, 59, 295
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,556,812,649,295, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
556:2x 2x 139
812:2x 2x 7x 29
649:11x 59
295:5x 59
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 5x 7x 59 = 16520
Therefore, the value for common factors is 16520.
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 = 54455040208800/(1x16520)
LCM = 54455040208800/16520
LCM = 3296309940
Thus, we can understand that the LCM of 630,556,812,649,295 is 3296309940.
