Given numbers are 977,741,942,548,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,741,942,548,642 is 6664640996364.
Find LCM of 977,741,942,548,642 with Prime Factorization
2 | 977, 741, 942, 548, 642 |
3 | 977, 741, 471, 274, 321 |
977, 247, 157, 274, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 977 x 247 x 157 x 274 x 107 = 6664640996364
Therefore, the lowest common multiple of 977,741,942,548,642 is 6664640996364.
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 741 x 942 x 548 x 642 = 239927075869104
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
741 : 1, 3, 13, 19, 39, 57, 247, 741
942 : 1, 2, 3, 6, 157, 314, 471, 942
548 : 1, 2, 4, 137, 274, 548
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,741,942,548,642, is 1.
Now, the common factors can be found like this.
977:977
741:3x 13x 19
942:2x 3x 157
548:2x 2x 137
642:2x 3x 107
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 239927075869104/(1x36)
LCM = 239927075869104/36
LCM = 6664640996364
Thus, we can understand that the LCM of 977,741,942,548,642 is 6664640996364.
