Given numbers are 322,638,968,257,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 322,638,968,257,940 is 272960758840.
Find LCM of 322,638,968,257,940 with Prime Factorization
2 | 322, 638, 968, 257, 940 |
2 | 161, 319, 484, 257, 470 |
11 | 161, 319, 242, 257, 235 |
161, 29, 22, 257, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 161 x 29 x 22 x 257 x 235 = 272960758840
Therefore, the lowest common multiple of 322,638,968,257,940 is 272960758840.
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.
322 x 638 x 968 x 257 x 940 = 48041093555840
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.
322 : 1, 2, 7, 14, 23, 46, 161, 322
638 : 1, 2, 11, 22, 29, 58, 319, 638
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
257 : 1, 257
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,638,968,257,940, is 1.
Now, the common factors can be found like this.
322:2x 7x 23
638:2x 11x 29
968:2x 2x 2x 11x 11
257:257
940:2x 2x 5x 47
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 11 = 176
Therefore, the value for common factors is 176.
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 = 48041093555840/(1x176)
LCM = 48041093555840/176
LCM = 272960758840
Thus, we can understand that the LCM of 322,638,968,257,940 is 272960758840.
