Given numbers are 802,171,989,194
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,171,989,194 is 13156443486.
Find LCM of 802,171,989,194 with Prime Factorization
2 | 802, 171, 989, 194 |
401, 171, 989, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 401 x 171 x 989 x 97 = 13156443486
Therefore, the lowest common multiple of 802,171,989,194 is 13156443486.
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.
802 x 171 x 989 x 194 = 26312886972
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.
802 : 1, 2, 401, 802
171 : 1, 3, 9, 19, 57, 171
989 : 1, 23, 43, 989
194 : 1, 2, 97, 194
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,171,989,194, is 1.
Now, the common factors can be found like this.
802:2x 401
171:3x 3x 19
989:23x 43
194:2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 26312886972/(1x2)
LCM = 26312886972/2
LCM = 13156443486
Thus, we can understand that the LCM of 802,171,989,194 is 13156443486.
