Find LCM of 644,222,196,989,377 with Prime Factorization
| 2 | 644, 222, 196, 989, 377 |
| 2 | 322, 111, 98, 989, 377 |
| 7 | 161, 111, 49, 989, 377 |
| 23 | 23, 111, 7, 989, 377 |
| 1, 111, 7, 43, 377 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 1 x 111 x 7 x 43 x 377 = 8111789868
Therefore, the lowest common multiple of 644,222,196,989,377 is 8111789868.
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.
644 x 222 x 196 x 989 x 377 = 10447985349984
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
222 : 1, 2, 3, 6, 37, 74, 111, 222
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
989 : 1, 23, 43, 989
377 : 1, 13, 29, 377
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,222,196,989,377, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
222:2x 3x 37
196:2x 2x 7x 7
989:23x 43
377:13x 29
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 7x 23 = 1288
Therefore, the value for common factors is 1288.
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 = 10447985349984/(1x1288)
LCM = 10447985349984/1288
LCM = 8111789868
Thus, we can understand that the LCM of 644,222,196,989,377 is 8111789868.
