Find LCM of 364,728,340,680 with Prime Factorization
2 | 364, 728, 340, 680 |
2 | 182, 364, 170, 340 |
2 | 91, 182, 85, 170 |
5 | 91, 91, 85, 85 |
7 | 91, 91, 17, 17 |
13 | 13, 13, 17, 17 |
17 | 1, 1, 17, 17 |
1, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 13 x 17 x 1 x 1 x 1 x 1 = 61880
Therefore, the lowest common multiple of 364,728,340,680 is 61880.
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.
364 x 728 x 340 x 680 = 61266150400
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,728,340,680, is 4.
Now, the common factors can be found like this.
364:2x 2x 7x 13
728:2x 2x 2x 7x 13
340:2x 2x 5x 17
680:2x 2x 2x 5x 17
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 5x 7x 13x 17 = 247520
Therefore, the value for common factors is 247520.
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 = 61266150400/(4x247520)
LCM = 61266150400/990080
LCM = 61880
Thus, we can understand that the LCM of 364,728,340,680 is 61880.
