Find LCM of 945,342,515,611,221 with Prime Factorization
| 3 | 945, 342, 515, 611, 221 |
| 3 | 315, 114, 515, 611, 221 |
| 5 | 105, 38, 515, 611, 221 |
| 13 | 21, 38, 103, 611, 221 |
| 21, 38, 103, 47, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 21 x 38 x 103 x 47 x 17 = 38418708510
Therefore, the lowest common multiple of 945,342,515,611,221 is 38418708510.
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.
945 x 342 x 515 x 611 x 221 = 22474944478350
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
515 : 1, 5, 103, 515
611 : 1, 13, 47, 611
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,342,515,611,221, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
342:2x 3x 3x 19
515:5x 103
611:13x 47
221:13x 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 3x 5x 13 = 585
Therefore, the value for common factors is 585.
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 = 22474944478350/(1x585)
LCM = 22474944478350/585
LCM = 38418708510
Thus, we can understand that the LCM of 945,342,515,611,221 is 38418708510.
