Given numbers are 921,627,220,614
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,627,220,614 is 3849780.
Find LCM of 921,627,220,614 with Prime Factorization
| 2 | 921, 627, 220, 614 |
| 3 | 921, 627, 110, 307 |
| 11 | 307, 209, 110, 307 |
| 307 | 307, 19, 10, 307 |
| 1, 19, 10, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 307 x 1 x 19 x 10 x 1 = 3849780
Therefore, the lowest common multiple of 921,627,220,614 is 3849780.
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.
921 x 627 x 220 x 614 = 78004242360
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.
921 : 1, 3, 307, 921
627 : 1, 3, 11, 19, 33, 57, 209, 627
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
614 : 1, 2, 307, 614
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,627,220,614, is 1.
Now, the common factors can be found like this.
921:3x 307
627:3x 11x 19
220:2x 2x 5x 11
614:2x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 307 = 20262
Therefore, the value for common factors is 20262.
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 = 78004242360/(1x20262)
LCM = 78004242360/20262
LCM = 3849780
Thus, we can understand that the LCM of 921,627,220,614 is 3849780.
