Given numbers are 986,978,169,444
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,978,169,444 is 6029817924.
Find LCM of 986,978,169,444 with Prime Factorization
| 2 | 986, 978, 169, 444 |
| 3 | 493, 489, 169, 222 |
| 493, 163, 169, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 493 x 163 x 169 x 74 = 6029817924
Therefore, the lowest common multiple of 986,978,169,444 is 6029817924.
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.
986 x 978 x 169 x 444 = 72357815088
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
978 : 1, 2, 3, 6, 163, 326, 489, 978
169 : 1, 13, 169
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,978,169,444, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
978:2x 3x 163
169:13x 13
444:2x 2x 3x 37
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 3 = 12
Therefore, the value for common factors is 12.
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 = 72357815088/(1x12)
LCM = 72357815088/12
LCM = 6029817924
Thus, we can understand that the LCM of 986,978,169,444 is 6029817924.
