Given numbers are 421,388,745,365
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,388,745,365 is 8883680980.
Find LCM of 421,388,745,365 with Prime Factorization
5 | 421, 388, 745, 365 |
421, 388, 149, 73 |
Multiply the prime numbers at the bottom and the left side.
5 x 421 x 388 x 149 x 73 = 8883680980
Therefore, the lowest common multiple of 421,388,745,365 is 8883680980.
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.
421 x 388 x 745 x 365 = 44418404900
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.
421 : 1, 421
388 : 1, 2, 4, 97, 194, 388
745 : 1, 5, 149, 745
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,388,745,365, is 1.
Now, the common factors can be found like this.
421:421
388:2x 2x 97
745:5x 149
365:5x 73
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 = 44418404900/(1x5)
LCM = 44418404900/5
LCM = 8883680980
Thus, we can understand that the LCM of 421,388,745,365 is 8883680980.
