Given numbers are 724,621,378,433
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,621,378,433 is 1362749724.
Find LCM of 724,621,378,433 with Prime Factorization
2 | 724, 621, 378, 433 |
3 | 362, 621, 189, 433 |
3 | 362, 207, 63, 433 |
3 | 362, 69, 21, 433 |
362, 23, 7, 433 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 362 x 23 x 7 x 433 = 1362749724
Therefore, the lowest common multiple of 724,621,378,433 is 1362749724.
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.
724 x 621 x 378 x 433 = 73588485096
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.
724 : 1, 2, 4, 181, 362, 724
621 : 1, 3, 9, 23, 27, 69, 207, 621
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
433 : 1, 433
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,621,378,433, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
621:3x 3x 3x 23
378:2x 3x 3x 3x 7
433:433
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 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 73588485096/(1x54)
LCM = 73588485096/54
LCM = 1362749724
Thus, we can understand that the LCM of 724,621,378,433 is 1362749724.
