Given numbers are 977,643,666,196
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,643,666,196 is 41002075548.
Find LCM of 977,643,666,196 with Prime Factorization
| 2 | 977, 643, 666, 196 |
| 977, 643, 333, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 977 x 643 x 333 x 98 = 41002075548
Therefore, the lowest common multiple of 977,643,666,196 is 41002075548.
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.
977 x 643 x 666 x 196 = 82004151096
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.
977 : 1, 977
643 : 1, 643
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,643,666,196, is 1.
Now, the common factors can be found like this.
977:977
643:643
666:2x 3x 3x 37
196:2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 82004151096/(1x2)
LCM = 82004151096/2
LCM = 41002075548
Thus, we can understand that the LCM of 977,643,666,196 is 41002075548.
