Find LCM of 942,612,491,747,228 with Prime Factorization
| 2 | 942, 612, 491, 747, 228 |
| 2 | 471, 306, 491, 747, 114 |
| 3 | 471, 153, 491, 747, 57 |
| 3 | 157, 51, 491, 249, 19 |
| 157, 17, 491, 83, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 157 x 17 x 491 x 83 x 19 = 74398513788
Therefore, the lowest common multiple of 942,612,491,747,228 is 74398513788.
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.
942 x 612 x 491 x 747 x 228 = 48210236934624
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
491 : 1, 491
747 : 1, 3, 9, 83, 249, 747
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,612,491,747,228, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
612:2x 2x 3x 3x 17
491:491
747:3x 3x 83
228:2x 2x 3x 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 3x 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 48210236934624/(1x648)
LCM = 48210236934624/648
LCM = 74398513788
Thus, we can understand that the LCM of 942,612,491,747,228 is 74398513788.
