Given numbers are 724,760,787,694,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,760,787,694,945 is 7099997216760.
Find LCM of 724,760,787,694,945 with Prime Factorization
| 2 | 724, 760, 787, 694, 945 |
| 2 | 362, 380, 787, 347, 945 |
| 5 | 181, 190, 787, 347, 945 |
| 181, 38, 787, 347, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 181 x 38 x 787 x 347 x 189 = 7099997216760
Therefore, the lowest common multiple of 724,760,787,694,945 is 7099997216760.
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 760 x 787 x 694 x 945 = 283999888670400
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
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
787 : 1, 787
694 : 1, 2, 347, 694
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,760,787,694,945, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
760:2x 2x 2x 5x 19
787:787
694:2x 347
945:3x 3x 3x 5x 7
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 5 = 40
Therefore, the value for common factors is 40.
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 = 283999888670400/(1x40)
LCM = 283999888670400/40
LCM = 7099997216760
Thus, we can understand that the LCM of 724,760,787,694,945 is 7099997216760.
