Given numbers are 101,240,246,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 101,240,246,721 is 716558640.
Find LCM of 101,240,246,721 with Prime Factorization
| 2 | 101, 240, 246, 721 |
| 3 | 101, 120, 123, 721 |
| 101, 40, 41, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 101 x 40 x 41 x 721 = 716558640
Therefore, the lowest common multiple of 101,240,246,721 is 716558640.
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.
101 x 240 x 246 x 721 = 4299351840
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.
101 : 1, 101
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
246 : 1, 2, 3, 6, 41, 82, 123, 246
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,240,246,721, is 1.
Now, the common factors can be found like this.
101:101
240:2x 2x 2x 2x 3x 5
246:2x 3x 41
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 4299351840/(1x6)
LCM = 4299351840/6
LCM = 716558640
Thus, we can understand that the LCM of 101,240,246,721 is 716558640.
