Given numbers are 978,310,256,611,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,310,256,611,775 is 59277753600.
Find LCM of 978,310,256,611,775 with Prime Factorization
| 2 | 978, 310, 256, 611, 775 |
| 5 | 489, 155, 128, 611, 775 |
| 31 | 489, 31, 128, 611, 155 |
| 489, 1, 128, 611, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 489 x 1 x 128 x 611 x 5 = 59277753600
Therefore, the lowest common multiple of 978,310,256,611,775 is 59277753600.
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.
978 x 310 x 256 x 611 x 775 = 36752207232000
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
310 : 1, 2, 5, 10, 31, 62, 155, 310
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
611 : 1, 13, 47, 611
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,310,256,611,775, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
310:2x 5x 31
256:2x 2x 2x 2x 2x 2x 2x 2
611:13x 47
775:5x 5x 31
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 5x 31 = 620
Therefore, the value for common factors is 620.
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 = 36752207232000/(1x620)
LCM = 36752207232000/620
LCM = 59277753600
Thus, we can understand that the LCM of 978,310,256,611,775 is 59277753600.
