Find LCM of 242,805,545,561,357 with Prime Factorization
| 3 | 242, 805, 545, 561, 357 |
| 5 | 242, 805, 545, 187, 119 |
| 7 | 242, 161, 109, 187, 119 |
| 11 | 242, 23, 109, 187, 17 |
| 17 | 22, 23, 109, 17, 17 |
| 22, 23, 109, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 17 x 22 x 23 x 109 x 1 x 1 = 1082948790
Therefore, the lowest common multiple of 242,805,545,561,357 is 1082948790.
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.
242 x 805 x 545 x 561 x 357 = 21263699491650
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.
242 : 1, 2, 11, 22, 121, 242
805 : 1, 5, 7, 23, 35, 115, 161, 805
545 : 1, 5, 109, 545
561 : 1, 3, 11, 17, 33, 51, 187, 561
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,805,545,561,357, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
805:5x 7x 23
545:5x 109
561:3x 11x 17
357:3x 7x 17
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 7x 11x 17 = 19635
Therefore, the value for common factors is 19635.
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 = 21263699491650/(1x19635)
LCM = 21263699491650/19635
LCM = 1082948790
Thus, we can understand that the LCM of 242,805,545,561,357 is 1082948790.
