Given numbers are 327,578,784,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 327,578,784,680 is 370451760.
Find LCM of 327,578,784,680 with Prime Factorization
2 | 327, 578, 784, 680 |
2 | 327, 289, 392, 340 |
2 | 327, 289, 196, 170 |
17 | 327, 289, 98, 85 |
327, 17, 98, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 327 x 17 x 98 x 5 = 370451760
Therefore, the lowest common multiple of 327,578,784,680 is 370451760.
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.
327 x 578 x 784 x 680 = 100762878720
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.
327 : 1, 3, 109, 327
578 : 1, 2, 17, 34, 289, 578
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,578,784,680, is 1.
Now, the common factors can be found like this.
327:3x 109
578:2x 17x 17
784:2x 2x 2x 2x 7x 7
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 17 = 272
Therefore, the value for common factors is 272.
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 = 100762878720/(1x272)
LCM = 100762878720/272
LCM = 370451760
Thus, we can understand that the LCM of 327,578,784,680 is 370451760.
