Given numbers are 685,631,764,393,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,631,764,393,545 is 14145957130980.
Find LCM of 685,631,764,393,545 with Prime Factorization
5 | 685, 631, 764, 393, 545 |
137, 631, 764, 393, 109 |
Multiply the prime numbers at the bottom and the left side.
5 x 137 x 631 x 764 x 393 x 109 = 14145957130980
Therefore, the lowest common multiple of 685,631,764,393,545 is 14145957130980.
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.
685 x 631 x 764 x 393 x 545 = 70729785654900
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.
685 : 1, 5, 137, 685
631 : 1, 631
764 : 1, 2, 4, 191, 382, 764
393 : 1, 3, 131, 393
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,631,764,393,545, is 1.
Now, the common factors can be found like this.
685:5x 137
631:631
764:2x 2x 191
393:3x 131
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 70729785654900/(1x5)
LCM = 70729785654900/5
LCM = 14145957130980
Thus, we can understand that the LCM of 685,631,764,393,545 is 14145957130980.
