Given numbers are 644,358,966,627
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,358,966,627 is 72278052.
Find LCM of 644,358,966,627 with Prime Factorization
2 | 644, 358, 966, 627 |
3 | 322, 179, 483, 627 |
7 | 322, 179, 161, 209 |
23 | 46, 179, 23, 209 |
2, 179, 1, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 2 x 179 x 1 x 209 = 72278052
Therefore, the lowest common multiple of 644,358,966,627 is 72278052.
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.
644 x 358 x 966 x 627 = 139641196464
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
358 : 1, 2, 179, 358
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
627 : 1, 3, 11, 19, 33, 57, 209, 627
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,358,966,627, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
358:2x 179
966:2x 3x 7x 23
627:3x 11x 19
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 3x 7x 23 = 1932
Therefore, the value for common factors is 1932.
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 = 139641196464/(1x1932)
LCM = 139641196464/1932
LCM = 72278052
Thus, we can understand that the LCM of 644,358,966,627 is 72278052.
