The LCM of 961,779,646,216,248 is 2748928968.
Find LCM of 961,779,646,216,248 with Prime Factorization
| 2 | 961, 779, 646, 216, 248 |
| 2 | 961, 779, 323, 108, 124 |
| 2 | 961, 779, 323, 54, 62 |
| 19 | 961, 779, 323, 27, 31 |
| 31 | 961, 41, 17, 27, 31 |
| 1, 41, 17, 27, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 31 x 1 x 41 x 17 x 27 x 31 = 2748928968
Therefore, the lowest common multiple of 961,779,646,216,248 is 2748928968.
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.
961 x 779 x 646 x 216 x 248 = 25905906594432
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.
961 : 1, 31, 961
779 : 1, 19, 41, 779
646 : 1, 2, 17, 19, 34, 38, 323, 646
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,779,646,216,248, is 1.
Now, the common factors can be found like this.
961:31x 31
779:19x 41
646:2x 17x 19
216:2x 2x 2x 3x 3x 3
248:2x 2x 2x 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 2x 2x 19x 31 = 9424
Therefore, the value for common factors is 9424.
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 = 25905906594432/(1x9424)
LCM = 25905906594432/9424
LCM = 2748928968
Thus, we can understand that the LCM of 961,779,646,216,248 is 2748928968.
