Find LCM of 392,354,791,144 with Prime Factorization
| 2 | 392, 354, 791, 144 |
| 2 | 196, 177, 791, 72 |
| 2 | 98, 177, 791, 36 |
| 3 | 49, 177, 791, 18 |
| 7 | 49, 59, 791, 6 |
| 7, 59, 113, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 59 x 113 x 6 = 47042352
Therefore, the lowest common multiple of 392,354,791,144 is 47042352.
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.
392 x 354 x 791 x 144 = 15806230272
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
354 : 1, 2, 3, 6, 59, 118, 177, 354
791 : 1, 7, 113, 791
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,354,791,144, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
354:2x 3x 59
791:7x 113
144:2x 2x 2x 2x 3x 3
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 = 15806230272/(1x336)
LCM = 15806230272/336
LCM = 47042352
Thus, we can understand that the LCM of 392,354,791,144 is 47042352.
