Find LCM of 723,874,690,475 with Prime Factorization
| 2 | 723, 874, 690, 475 |
| 3 | 723, 437, 345, 475 |
| 5 | 241, 437, 115, 475 |
| 19 | 241, 437, 23, 95 |
| 23 | 241, 23, 23, 5 |
| 241, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 23 x 241 x 1 x 1 x 5 = 15797550
Therefore, the lowest common multiple of 723,874,690,475 is 15797550.
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.
723 x 874 x 690 x 475 = 207105880500
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.
723 : 1, 3, 241, 723
874 : 1, 2, 19, 23, 38, 46, 437, 874
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,874,690,475, is 1.
Now, the common factors can be found like this.
723:3x 241
874:2x 19x 23
690:2x 3x 5x 23
475:5x 5x 19
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 19x 23 = 13110
Therefore, the value for common factors is 13110.
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 = 207105880500/(1x13110)
LCM = 207105880500/13110
LCM = 15797550
Thus, we can understand that the LCM of 723,874,690,475 is 15797550.
