The LCM of 376,216,997,978 is 1649811672.
Find LCM of 376,216,997,978 with Prime Factorization
| 2 | 376, 216, 997, 978 |
| 2 | 188, 108, 997, 489 |
| 2 | 94, 54, 997, 489 |
| 3 | 47, 27, 997, 489 |
| 47, 9, 997, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 47 x 9 x 997 x 163 = 1649811672
Therefore, the lowest common multiple of 376,216,997,978 is 1649811672.
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.
376 x 216 x 997 x 978 = 79190960256
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.
376 : 1, 2, 4, 8, 47, 94, 188, 376
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
997 : 1, 997
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 376,216,997,978, is 1.
Now, the common factors can be found like this.
376:2x 2x 2x 47
216:2x 2x 2x 3x 3x 3
997:997
978:2x 3x 163
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 79190960256/(1x48)
LCM = 79190960256/48
LCM = 1649811672
Thus, we can understand that the LCM of 376,216,997,978 is 1649811672.
