Find LCM of 685,174,490,322,336 with Prime Factorization
| 2 | 685, 174, 490, 322, 336 |
| 3 | 685, 87, 245, 161, 168 |
| 5 | 685, 29, 245, 161, 56 |
| 7 | 137, 29, 49, 161, 56 |
| 137, 29, 7, 23, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 137 x 29 x 7 x 23 x 8 = 1074617040
Therefore, the lowest common multiple of 685,174,490,322,336 is 1074617040.
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.
685 x 174 x 490 x 322 x 336 = 6318748195200
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.
685 : 1, 5, 137, 685
174 : 1, 2, 3, 6, 29, 58, 87, 174
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
322 : 1, 2, 7, 14, 23, 46, 161, 322
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,174,490,322,336, is 1.
Now, the common factors can be found like this.
685:5x 137
174:2x 3x 29
490:2x 5x 7x 7
322:2x 7x 23
336:2x 2x 2x 2x 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 3x 5x 7x 7 = 5880
Therefore, the value for common factors is 5880.
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 = 6318748195200/(1x5880)
LCM = 6318748195200/5880
LCM = 1074617040
Thus, we can understand that the LCM of 685,174,490,322,336 is 1074617040.
