Given numbers are 787,856,666,973,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,856,666,973,428 is 218275791048.
Find LCM of 787,856,666,973,428 with Prime Factorization
2 | 787, 856, 666, 973, 428 |
2 | 787, 428, 333, 973, 214 |
107 | 787, 107, 333, 973, 214 |
787, 1, 333, 973, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 107 x 787 x 1 x 333 x 973 x 2 = 218275791048
Therefore, the lowest common multiple of 787,856,666,973,428 is 218275791048.
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.
787 x 856 x 666 x 973 x 428 = 186844077137088
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.
787 : 1, 787
856 : 1, 2, 4, 8, 107, 214, 428, 856
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
973 : 1, 7, 139, 973
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,856,666,973,428, is 1.
Now, the common factors can be found like this.
787:787
856:2x 2x 2x 107
666:2x 3x 3x 37
973:7x 139
428:2x 2x 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 2x 107 = 856
Therefore, the value for common factors is 856.
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 = 186844077137088/(1x856)
LCM = 186844077137088/856
LCM = 218275791048
Thus, we can understand that the LCM of 787,856,666,973,428 is 218275791048.
