Given numbers are 994,649,620,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 994,649,620,775 is 999914300.
Find LCM of 994,649,620,775 with Prime Factorization
| 2 | 994, 649, 620, 775 |
| 5 | 497, 649, 310, 775 |
| 31 | 497, 649, 62, 155 |
| 497, 649, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 497 x 649 x 2 x 5 = 999914300
Therefore, the lowest common multiple of 994,649,620,775 is 999914300.
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.
994 x 649 x 620 x 775 = 309973433000
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
649 : 1, 11, 59, 649
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,649,620,775, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
649:11x 59
620:2x 2x 5x 31
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 31 = 310
Therefore, the value for common factors is 310.
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 = 309973433000/(1x310)
LCM = 309973433000/310
LCM = 999914300
Thus, we can understand that the LCM of 994,649,620,775 is 999914300.
