Find LCM of 312,384,660,680,724 with Prime Factorization
2 | 312, 384, 660, 680, 724 |
2 | 156, 192, 330, 340, 362 |
2 | 78, 96, 165, 170, 181 |
3 | 39, 48, 165, 85, 181 |
5 | 13, 16, 55, 85, 181 |
13, 16, 11, 17, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 16 x 11 x 17 x 181 = 844821120
Therefore, the lowest common multiple of 312,384,660,680,724 is 844821120.
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.
312 x 384 x 660 x 680 x 724 = 38929357209600
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
724 : 1, 2, 4, 181, 362, 724
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,384,660,680,724, is 4.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
384:2x 2x 2x 2x 2x 2x 2x 3
660:2x 2x 3x 5x 11
680:2x 2x 2x 5x 17
724:2x 2x 181
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 2x 2x 3x 3x 5 = 11520
Therefore, the value for common factors is 11520.
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 = 38929357209600/(4x11520)
LCM = 38929357209600/46080
LCM = 844821120
Thus, we can understand that the LCM of 312,384,660,680,724 is 844821120.
