Find LCM of 209,888,781,611,880 with Prime Factorization
| 2 | 209, 888, 781, 611, 880 |
| 2 | 209, 444, 781, 611, 440 |
| 2 | 209, 222, 781, 611, 220 |
| 11 | 209, 111, 781, 611, 110 |
| 19, 111, 71, 611, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 19 x 111 x 71 x 611 x 10 = 80511665520
Therefore, the lowest common multiple of 209,888,781,611,880 is 80511665520.
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.
209 x 888 x 781 x 611 x 880 = 77935292223360
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.
209 : 1, 11, 19, 209
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
781 : 1, 11, 71, 781
611 : 1, 13, 47, 611
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,888,781,611,880, is 1.
Now, the common factors can be found like this.
209:11x 19
888:2x 2x 2x 3x 37
781:11x 71
611:13x 47
880:2x 2x 2x 2x 5x 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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 77935292223360/(1x968)
LCM = 77935292223360/968
LCM = 80511665520
Thus, we can understand that the LCM of 209,888,781,611,880 is 80511665520.
