Given numbers are 688,303,653,772,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,303,653,772,822 is 3599333795472.
Find LCM of 688,303,653,772,822 with Prime Factorization
| 2 | 688, 303, 653, 772, 822 |
| 2 | 344, 303, 653, 386, 411 |
| 3 | 172, 303, 653, 193, 411 |
| 172, 101, 653, 193, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 172 x 101 x 653 x 193 x 137 = 3599333795472
Therefore, the lowest common multiple of 688,303,653,772,822 is 3599333795472.
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.
688 x 303 x 653 x 772 x 822 = 86384011091328
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
303 : 1, 3, 101, 303
653 : 1, 653
772 : 1, 2, 4, 193, 386, 772
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,303,653,772,822, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
303:3x 101
653:653
772:2x 2x 193
822:2x 3x 137
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 3 = 24
Therefore, the value for common factors is 24.
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 = 86384011091328/(1x24)
LCM = 86384011091328/24
LCM = 3599333795472
Thus, we can understand that the LCM of 688,303,653,772,822 is 3599333795472.
