Given numbers are 727,124,892,420,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 727,124,892,420,649 is 1369919207580.
Find LCM of 727,124,892,420,649 with Prime Factorization
| 2 | 727, 124, 892, 420, 649 |
| 2 | 727, 62, 446, 210, 649 |
| 727, 31, 223, 105, 649 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 727 x 31 x 223 x 105 x 649 = 1369919207580
Therefore, the lowest common multiple of 727,124,892,420,649 is 1369919207580.
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.
727 x 124 x 892 x 420 x 649 = 21918707321280
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.
727 : 1, 727
124 : 1, 2, 4, 31, 62, 124
892 : 1, 2, 4, 223, 446, 892
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,124,892,420,649, is 1.
Now, the common factors can be found like this.
727:727
124:2x 2x 31
892:2x 2x 223
420:2x 2x 3x 5x 7
649:11x 59
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 21918707321280/(1x16)
LCM = 21918707321280/16
LCM = 1369919207580
Thus, we can understand that the LCM of 727,124,892,420,649 is 1369919207580.
