Find LCM of 554,989,645,894,965 with Prime Factorization
| 2 | 554, 989, 645, 894, 965 |
| 3 | 277, 989, 645, 447, 965 |
| 5 | 277, 989, 215, 149, 965 |
| 43 | 277, 989, 43, 149, 193 |
| 277, 23, 1, 149, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 277 x 23 x 1 x 149 x 193 = 236341992630
Therefore, the lowest common multiple of 554,989,645,894,965 is 236341992630.
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.
554 x 989 x 645 x 894 x 965 = 304881170492700
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.
554 : 1, 2, 277, 554
989 : 1, 23, 43, 989
645 : 1, 3, 5, 15, 43, 129, 215, 645
894 : 1, 2, 3, 6, 149, 298, 447, 894
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,989,645,894,965, is 1.
Now, the common factors can be found like this.
554:2x 277
989:23x 43
645:3x 5x 43
894:2x 3x 149
965:5x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 43 = 1290
Therefore, the value for common factors is 1290.
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 = 304881170492700/(1x1290)
LCM = 304881170492700/1290
LCM = 236341992630
Thus, we can understand that the LCM of 554,989,645,894,965 is 236341992630.
