Given numbers are 662,287,847,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,287,847,492 is 137935644.
Find LCM of 662,287,847,492 with Prime Factorization
| 2 | 662, 287, 847, 492 |
| 7 | 331, 287, 847, 246 |
| 41 | 331, 41, 121, 246 |
| 331, 1, 121, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 331 x 1 x 121 x 6 = 137935644
Therefore, the lowest common multiple of 662,287,847,492 is 137935644.
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.
662 x 287 x 847 x 492 = 79175059656
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.
662 : 1, 2, 331, 662
287 : 1, 7, 41, 287
847 : 1, 7, 11, 77, 121, 847
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,287,847,492, is 1.
Now, the common factors can be found like this.
662:2x 331
287:7x 41
847:7x 11x 11
492:2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 41 = 574
Therefore, the value for common factors is 574.
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 = 79175059656/(1x574)
LCM = 79175059656/574
LCM = 137935644
Thus, we can understand that the LCM of 662,287,847,492 is 137935644.
