The LCM of 357,690,406,725 is 11905950.
Find LCM of 357,690,406,725 with Prime Factorization
| 2 | 357, 690, 406, 725 |
| 3 | 357, 345, 203, 725 |
| 5 | 119, 115, 203, 725 |
| 7 | 119, 23, 203, 145 |
| 29 | 17, 23, 29, 145 |
| 17, 23, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 29 x 17 x 23 x 1 x 5 = 11905950
Therefore, the lowest common multiple of 357,690,406,725 is 11905950.
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.
357 x 690 x 406 x 725 = 72507235500
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
406 : 1, 2, 7, 14, 29, 58, 203, 406
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,690,406,725, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
690:2x 3x 5x 23
406:2x 7x 29
725:5x 5x 29
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 7x 29 = 6090
Therefore, the value for common factors is 6090.
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 = 72507235500/(1x6090)
LCM = 72507235500/6090
LCM = 11905950
Thus, we can understand that the LCM of 357,690,406,725 is 11905950.
