The LCM of 757,748,638,958,836 is 149446101244.
Find LCM of 757,748,638,958,836 with Prime Factorization
| 2 | 757, 748, 638, 958, 836 |
| 2 | 757, 374, 319, 479, 418 |
| 11 | 757, 187, 319, 479, 209 |
| 757, 17, 29, 479, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 757 x 17 x 29 x 479 x 19 = 149446101244
Therefore, the lowest common multiple of 757,748,638,958,836 is 149446101244.
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.
757 x 748 x 638 x 958 x 836 = 289327652008384
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.
757 : 1, 757
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
638 : 1, 2, 11, 22, 29, 58, 319, 638
958 : 1, 2, 479, 958
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 757,748,638,958,836, is 1.
Now, the common factors can be found like this.
757:757
748:2x 2x 11x 17
638:2x 11x 29
958:2x 479
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 2x 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 289327652008384/(1x1936)
LCM = 289327652008384/1936
LCM = 149446101244
Thus, we can understand that the LCM of 757,748,638,958,836 is 149446101244.
