Given numbers are 337,392,978,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 337,392,978,160 is 1291977120.
Find LCM of 337,392,978,160 with Prime Factorization
| 2 | 337, 392, 978, 160 |
| 2 | 337, 196, 489, 80 |
| 2 | 337, 98, 489, 40 |
| 337, 49, 489, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 337 x 49 x 489 x 20 = 1291977120
Therefore, the lowest common multiple of 337,392,978,160 is 1291977120.
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.
337 x 392 x 978 x 160 = 20671633920
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.
337 : 1, 337
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
978 : 1, 2, 3, 6, 163, 326, 489, 978
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 337,392,978,160, is 1.
Now, the common factors can be found like this.
337:337
392:2x 2x 2x 7x 7
978:2x 3x 163
160:2x 2x 2x 2x 2x 5
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 20671633920/(1x16)
LCM = 20671633920/16
LCM = 1291977120
Thus, we can understand that the LCM of 337,392,978,160 is 1291977120.
