The LCM of 977,336,746,168 is 122445456.
Find LCM of 977,336,746,168 with Prime Factorization
| 2 | 977, 336, 746, 168 |
| 2 | 977, 168, 373, 84 |
| 2 | 977, 42, 373, 84 |
| 3 | 977, 21, 373, 42 |
| 7 | 977, 7, 373, 14 |
| 977, 1, 373, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 977 x 1 x 373 x 2 = 122445456
Therefore, the lowest common multiple of 977,336,746,168 is 122445456.
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.
977 x 336 x 746 x 168 = 41141673216
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.
977 : 1, 977
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
746 : 1, 2, 373, 746
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,336,746,168, is 1.
Now, the common factors can be found like this.
977:977
336:2x 2x 2x 2x 3x 7
746:2x 373
168:2x 2x 2x 3x 7
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 41141673216/(1x336)
LCM = 41141673216/336
LCM = 122445456
Thus, we can understand that the LCM of 977,336,746,168 is 122445456.
