Given numbers are 389,989,742,329,496
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,989,742,329,496 is 3327356518192.
Find LCM of 389,989,742,329,496 with Prime Factorization
| 2 | 389, 989, 742, 329, 496 |
| 7 | 389, 989, 371, 329, 248 |
| 389, 989, 53, 47, 248 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 389 x 989 x 53 x 47 x 248 = 3327356518192
Therefore, the lowest common multiple of 389,989,742,329,496 is 3327356518192.
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.
389 x 989 x 742 x 329 x 496 = 46582991254688
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.
389 : 1, 389
989 : 1, 23, 43, 989
742 : 1, 2, 7, 14, 53, 106, 371, 742
329 : 1, 7, 47, 329
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,989,742,329,496, is 1.
Now, the common factors can be found like this.
389:389
989:23x 43
742:2x 7x 53
329:7x 47
496:2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 46582991254688/(1x14)
LCM = 46582991254688/14
LCM = 3327356518192
Thus, we can understand that the LCM of 389,989,742,329,496 is 3327356518192.
