The LCM of 745,994,868,836 is 9595787740.
Find LCM of 745,994,868,836 with Prime Factorization
| 2 | 745, 994, 868, 836 |
| 2 | 745, 497, 434, 418 |
| 7 | 745, 497, 217, 209 |
| 745, 71, 31, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 745 x 71 x 31 x 209 = 9595787740
Therefore, the lowest common multiple of 745,994,868,836 is 9595787740.
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.
745 x 994 x 868 x 836 = 537364113440
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.
745 : 1, 5, 149, 745
994 : 1, 2, 7, 14, 71, 142, 497, 994
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,994,868,836, is 1.
Now, the common factors can be found like this.
745:5x 149
994:2x 7x 71
868:2x 2x 7x 31
836:2x 2x 11x 19
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 7 = 56
Therefore, the value for common factors is 56.
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 = 537364113440/(1x56)
LCM = 537364113440/56
LCM = 9595787740
Thus, we can understand that the LCM of 745,994,868,836 is 9595787740.
