Given numbers are 642,595,863,988,736
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,595,863,988,736 is 29964536303520.
Find LCM of 642,595,863,988,736 with Prime Factorization
| 2 | 642, 595, 863, 988, 736 |
| 2 | 321, 595, 863, 494, 368 |
| 321, 595, 863, 247, 184 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 321 x 595 x 863 x 247 x 184 = 29964536303520
Therefore, the lowest common multiple of 642,595,863,988,736 is 29964536303520.
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.
642 x 595 x 863 x 988 x 736 = 239716290428160
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
595 : 1, 5, 7, 17, 35, 85, 119, 595
863 : 1, 863
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,595,863,988,736, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
595:5x 7x 17
863:863
988:2x 2x 13x 19
736:2x 2x 2x 2x 2x 23
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 2 = 8
Therefore, the value for common factors is 8.
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 = 239716290428160/(1x8)
LCM = 239716290428160/8
LCM = 29964536303520
Thus, we can understand that the LCM of 642,595,863,988,736 is 29964536303520.
