Given numbers are 994,989,516,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 994,989,516,970 is 2860722060.
Find LCM of 994,989,516,970 with Prime Factorization
| 2 | 994, 989, 516, 970 |
| 43 | 497, 989, 258, 485 |
| 497, 23, 6, 485 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 497 x 23 x 6 x 485 = 2860722060
Therefore, the lowest common multiple of 994,989,516,970 is 2860722060.
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 989 x 516 x 970 = 492044194320
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
989 : 1, 23, 43, 989
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,989,516,970, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
989:23x 43
516:2x 2x 3x 43
970:2x 5x 97
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 43 = 172
Therefore, the value for common factors is 172.
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 = 492044194320/(1x172)
LCM = 492044194320/172
LCM = 2860722060
Thus, we can understand that the LCM of 994,989,516,970 is 2860722060.
