Given numbers are 743,219,420,949,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,219,420,949,611 is 13918812180.
Find LCM of 743,219,420,949,611 with Prime Factorization
| 3 | 743, 219, 420, 949, 611 |
| 13 | 743, 73, 140, 949, 611 |
| 73 | 743, 73, 140, 73, 47 |
| 743, 1, 140, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 73 x 743 x 1 x 140 x 1 x 47 = 13918812180
Therefore, the lowest common multiple of 743,219,420,949,611 is 13918812180.
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.
743 x 219 x 420 x 949 x 611 = 39626858276460
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.
743 : 1, 743
219 : 1, 3, 73, 219
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
949 : 1, 13, 73, 949
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,219,420,949,611, is 1.
Now, the common factors can be found like this.
743:743
219:3x 73
420:2x 2x 3x 5x 7
949:13x 73
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 73 = 2847
Therefore, the value for common factors is 2847.
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 = 39626858276460/(1x2847)
LCM = 39626858276460/2847
LCM = 13918812180
Thus, we can understand that the LCM of 743,219,420,949,611 is 13918812180.
