Given numbers are 196,676,741,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 196,676,741,720 is 113284080.
Find LCM of 196,676,741,720 with Prime Factorization
| 2 | 196, 676, 741, 720 |
| 2 | 98, 338, 741, 360 |
| 3 | 49, 169, 741, 180 |
| 13 | 49, 169, 247, 60 |
| 49, 13, 19, 60 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 49 x 13 x 19 x 60 = 113284080
Therefore, the lowest common multiple of 196,676,741,720 is 113284080.
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.
196 x 676 x 741 x 720 = 70689265920
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.
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
741 : 1, 3, 13, 19, 39, 57, 247, 741
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,676,741,720, is 1.
Now, the common factors can be found like this.
196:2x 2x 7x 7
676:2x 2x 13x 13
741:3x 13x 19
720:2x 2x 2x 2x 3x 3x 5
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 2x 3x 13 = 624
Therefore, the value for common factors is 624.
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 = 70689265920/(1x624)
LCM = 70689265920/624
LCM = 113284080
Thus, we can understand that the LCM of 196,676,741,720 is 113284080.
