Given numbers are 694,978,798,167
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,978,798,167 is 7537658226.
Find LCM of 694,978,798,167 with Prime Factorization
| 2 | 694, 978, 798, 167 |
| 3 | 347, 489, 399, 167 |
| 347, 163, 133, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 347 x 163 x 133 x 167 = 7537658226
Therefore, the lowest common multiple of 694,978,798,167 is 7537658226.
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.
694 x 978 x 798 x 167 = 90451898712
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.
694 : 1, 2, 347, 694
978 : 1, 2, 3, 6, 163, 326, 489, 978
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
167 : 1, 167
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,978,798,167, is 1.
Now, the common factors can be found like this.
694:2x 347
978:2x 3x 163
798:2x 3x 7x 19
167:167
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 = 90451898712/(1x12)
LCM = 90451898712/12
LCM = 7537658226
Thus, we can understand that the LCM of 694,978,798,167 is 7537658226.
