Given numbers are 103,676,838,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,676,838,688 is 5017950704.
Find LCM of 103,676,838,688 with Prime Factorization
| 2 | 103, 676, 838, 688 |
| 2 | 103, 338, 419, 344 |
| 103, 169, 419, 172 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 103 x 169 x 419 x 172 = 5017950704
Therefore, the lowest common multiple of 103,676,838,688 is 5017950704.
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.
103 x 676 x 838 x 688 = 40143605632
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.
103 : 1, 103
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
838 : 1, 2, 419, 838
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,676,838,688, is 1.
Now, the common factors can be found like this.
103:103
676:2x 2x 13x 13
838:2x 419
688:2x 2x 2x 2x 43
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 = 40143605632/(1x8)
LCM = 40143605632/8
LCM = 5017950704
Thus, we can understand that the LCM of 103,676,838,688 is 5017950704.
