Find LCM of 324,989,690,641,325 with Prime Factorization
| 2 | 324, 989, 690, 641, 325 |
| 3 | 162, 989, 345, 641, 325 |
| 5 | 54, 989, 115, 641, 325 |
| 23 | 54, 989, 23, 641, 65 |
| 54, 43, 1, 641, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 54 x 43 x 1 x 641 x 65 = 66754829700
Therefore, the lowest common multiple of 324,989,690,641,325 is 66754829700.
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.
324 x 989 x 690 x 641 x 325 = 46060832493000
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.
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
989 : 1, 23, 43, 989
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
641 : 1, 641
325 : 1, 5, 13, 25, 65, 325
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 324,989,690,641,325, is 1.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
989:23x 43
690:2x 3x 5x 23
641:641
325:5x 5x 13
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 23 = 690
Therefore, the value for common factors is 690.
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 = 46060832493000/(1x690)
LCM = 46060832493000/690
LCM = 66754829700
Thus, we can understand that the LCM of 324,989,690,641,325 is 66754829700.
