Given numbers are 977,754,451,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,754,451,820 is 3322327580.
Find LCM of 977,754,451,820 with Prime Factorization
2 | 977, 754, 451, 820 |
41 | 977, 377, 451, 410 |
977, 377, 11, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 41 x 977 x 377 x 11 x 10 = 3322327580
Therefore, the lowest common multiple of 977,754,451,820 is 3322327580.
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 754 x 451 x 820 = 272430861560
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
754 : 1, 2, 13, 26, 29, 58, 377, 754
451 : 1, 11, 41, 451
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,754,451,820, is 1.
Now, the common factors can be found like this.
977:977
754:2x 13x 29
451:11x 41
820:2x 2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 41 = 82
Therefore, the value for common factors is 82.
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 = 272430861560/(1x82)
LCM = 272430861560/82
LCM = 3322327580
Thus, we can understand that the LCM of 977,754,451,820 is 3322327580.
