Find LCM of 548,639,145,945,217 with Prime Factorization
3 | 548, 639, 145, 945, 217 |
3 | 548, 213, 145, 315, 217 |
5 | 548, 71, 145, 105, 217 |
7 | 548, 71, 29, 21, 217 |
548, 71, 29, 3, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 548 x 71 x 29 x 3 x 31 = 33054485940
Therefore, the lowest common multiple of 548,639,145,945,217 is 33054485940.
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.
548 x 639 x 145 x 945 x 217 = 10412163071100
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.
548 : 1, 2, 4, 137, 274, 548
639 : 1, 3, 9, 71, 213, 639
145 : 1, 5, 29, 145
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,639,145,945,217, is 1.
Now, the common factors can be found like this.
548:2x 2x 137
639:3x 3x 71
145:5x 29
945:3x 3x 3x 5x 7
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 10412163071100/(1x315)
LCM = 10412163071100/315
LCM = 33054485940
Thus, we can understand that the LCM of 548,639,145,945,217 is 33054485940.
