Given numbers are 646,227,529,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,227,529,437 is 77573618.
Find LCM of 646,227,529,437 with Prime Factorization
19 | 646, 227, 529, 437 |
23 | 34, 227, 529, 23 |
34, 227, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
19 x 23 x 34 x 227 x 1 x 23 = 77573618
Therefore, the lowest common multiple of 646,227,529,437 is 77573618.
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.
646 x 227 x 529 x 437 = 33899671066
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
227 : 1, 227
529 : 1, 23, 529
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,227,529,437, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
227:227
529:23x 23
437:19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 23 = 437
Therefore, the value for common factors is 437.
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 = 33899671066/(1x437)
LCM = 33899671066/437
LCM = 77573618
Thus, we can understand that the LCM of 646,227,529,437 is 77573618.
