Given numbers are 678,695,148,561,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,695,148,561,676 is 1101982072620.
Find LCM of 678,695,148,561,676 with Prime Factorization
| 2 | 678, 695, 148, 561, 676 |
| 2 | 339, 695, 74, 561, 338 |
| 3 | 339, 695, 37, 561, 169 |
| 113, 695, 37, 187, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 113 x 695 x 37 x 187 x 169 = 1101982072620
Therefore, the lowest common multiple of 678,695,148,561,676 is 1101982072620.
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.
678 x 695 x 148 x 561 x 676 = 26447569742880
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
695 : 1, 5, 139, 695
148 : 1, 2, 4, 37, 74, 148
561 : 1, 3, 11, 17, 33, 51, 187, 561
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,695,148,561,676, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
695:5x 139
148:2x 2x 37
561:3x 11x 17
676:2x 2x 13x 13
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 3 = 24
Therefore, the value for common factors is 24.
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 = 26447569742880/(1x24)
LCM = 26447569742880/24
LCM = 1101982072620
Thus, we can understand that the LCM of 678,695,148,561,676 is 1101982072620.
