Find LCM of 525,125,345,247,641 with Prime Factorization
| 3 | 525, 125, 345, 247, 641 |
| 5 | 175, 125, 115, 247, 641 |
| 5 | 35, 25, 23, 247, 641 |
| 7, 5, 23, 247, 641 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 7 x 5 x 23 x 247 x 641 = 9558992625
Therefore, the lowest common multiple of 525,125,345,247,641 is 9558992625.
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.
525 x 125 x 345 x 247 x 641 = 3584622234375
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
125 : 1, 5, 25, 125
345 : 1, 3, 5, 15, 23, 69, 115, 345
247 : 1, 13, 19, 247
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,125,345,247,641, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
125:5x 5x 5
345:3x 5x 23
247:13x 19
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 5 = 375
Therefore, the value for common factors is 375.
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 = 3584622234375/(1x375)
LCM = 3584622234375/375
LCM = 9558992625
Thus, we can understand that the LCM of 525,125,345,247,641 is 9558992625.
