Given numbers are 638,247,319,616,739
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,247,319,616,739 is 3260769512.
Find LCM of 638,247,319,616,739 with Prime Factorization
| 2 | 638, 247, 319, 616, 739 |
| 11 | 319, 247, 319, 308, 739 |
| 29 | 29, 247, 29, 28, 739 |
| 1, 247, 1, 28, 739 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 1 x 247 x 1 x 28 x 739 = 3260769512
Therefore, the lowest common multiple of 638,247,319,616,739 is 3260769512.
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.
638 x 247 x 319 x 616 x 739 = 22884080435216
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
247 : 1, 13, 19, 247
319 : 1, 11, 29, 319
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
739 : 1, 739
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,247,319,616,739, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
247:13x 19
319:11x 29
616:2x 2x 2x 7x 11
739:739
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 29 = 7018
Therefore, the value for common factors is 7018.
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 = 22884080435216/(1x7018)
LCM = 22884080435216/7018
LCM = 3260769512
Thus, we can understand that the LCM of 638,247,319,616,739 is 3260769512.
