Find LCM of 168,836,688,707,611 with Prime Factorization
| 2 | 168, 836, 688, 707, 611 |
| 2 | 84, 418, 344, 707, 611 |
| 2 | 42, 209, 172, 707, 611 |
| 7 | 21, 209, 86, 707, 611 |
| 3, 209, 86, 101, 611 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 3 x 209 x 86 x 101 x 611 = 186344510352
Therefore, the lowest common multiple of 168,836,688,707,611 is 186344510352.
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.
168 x 836 x 688 x 707 x 611 = 41741170318848
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
707 : 1, 7, 101, 707
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,836,688,707,611, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
836:2x 2x 11x 19
688:2x 2x 2x 2x 43
707:7x 101
611:13x 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 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 41741170318848/(1x224)
LCM = 41741170318848/224
LCM = 186344510352
Thus, we can understand that the LCM of 168,836,688,707,611 is 186344510352.
