Find LCM of 220,394,788,516,968 with Prime Factorization
2 | 220, 394, 788, 516, 968 |
2 | 110, 197, 394, 258, 484 |
11 | 55, 197, 197, 129, 242 |
197 | 5, 197, 197, 129, 22 |
5, 1, 1, 129, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 197 x 5 x 1 x 1 x 129 x 22 = 122998920
Therefore, the lowest common multiple of 220,394,788,516,968 is 122998920.
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.
220 x 394 x 788 x 516 x 968 = 34116948433920
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
394 : 1, 2, 197, 394
788 : 1, 2, 4, 197, 394, 788
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,394,788,516,968, is 2.
Now, the common factors can be found like this.
220:2x 2x 5x 11
394:2x 197
788:2x 2x 197
516:2x 2x 3x 43
968:2x 2x 2x 11x 11
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 11x 197 = 138688
Therefore, the value for common factors is 138688.
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 = 34116948433920/(2x138688)
LCM = 34116948433920/277376
LCM = 122998920
Thus, we can understand that the LCM of 220,394,788,516,968 is 122998920.
