Given numbers are 538,628,836,989,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,628,836,989,774 is 314265719988.
Find LCM of 538,628,836,989,774 with Prime Factorization
| 2 | 538, 628, 836, 989, 774 |
| 2 | 269, 314, 418, 989, 387 |
| 43 | 269, 157, 209, 989, 387 |
| 269, 157, 209, 23, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 269 x 157 x 209 x 23 x 9 = 314265719988
Therefore, the lowest common multiple of 538,628,836,989,774 is 314265719988.
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.
538 x 628 x 836 x 989 x 774 = 216214815351744
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.
538 : 1, 2, 269, 538
628 : 1, 2, 4, 157, 314, 628
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
989 : 1, 23, 43, 989
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,628,836,989,774, is 1.
Now, the common factors can be found like this.
538:2x 269
628:2x 2x 157
836:2x 2x 11x 19
989:23x 43
774:2x 3x 3x 43
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 43 = 688
Therefore, the value for common factors is 688.
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 = 216214815351744/(1x688)
LCM = 216214815351744/688
LCM = 314265719988
Thus, we can understand that the LCM of 538,628,836,989,774 is 314265719988.
