Given numbers are 627,221,629,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 627,221,629,644 is 3301774476.
Find LCM of 627,221,629,644 with Prime Factorization
17 | 627, 221, 629, 644 |
627, 13, 37, 644 |
Multiply the prime numbers at the bottom and the left side.
17 x 627 x 13 x 37 x 644 = 3301774476
Therefore, the lowest common multiple of 627,221,629,644 is 3301774476.
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.
627 x 221 x 629 x 644 = 56130166092
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.
627 : 1, 3, 11, 19, 33, 57, 209, 627
221 : 1, 13, 17, 221
629 : 1, 17, 37, 629
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,221,629,644, is 1.
Now, the common factors can be found like this.
627:3x 11x 19
221:13x 17
629:17x 37
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 56130166092/(1x17)
LCM = 56130166092/17
LCM = 3301774476
Thus, we can understand that the LCM of 627,221,629,644 is 3301774476.
