Find LCM of 520,104,641,108,378 with Prime Factorization
| 2 | 520, 104, 641, 108, 378 |
| 2 | 260, 52, 641, 54, 189 |
| 2 | 130, 26, 641, 27, 189 |
| 3 | 65, 13, 641, 27, 189 |
| 3 | 65, 13, 641, 9, 63 |
| 3 | 65, 13, 641, 3, 21 |
| 13 | 65, 13, 641, 1, 7 |
| 5, 1, 641, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 13 x 5 x 1 x 641 x 1 x 7 = 62997480
Therefore, the lowest common multiple of 520,104,641,108,378 is 62997480.
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.
520 x 104 x 641 x 108 x 378 = 1415175390720
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
104 : 1, 2, 4, 8, 13, 26, 52, 104
641 : 1, 641
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,104,641,108,378, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
104:2x 2x 2x 13
641:641
108:2x 2x 3x 3x 3
378:2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 3x 3x 3x 13 = 22464
Therefore, the value for common factors is 22464.
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 = 1415175390720/(1x22464)
LCM = 1415175390720/22464
LCM = 62997480
Thus, we can understand that the LCM of 520,104,641,108,378 is 62997480.
