Given numbers are 719,728,805,945,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 719,728,805,945,755 is 245413710360.
Find LCM of 719,728,805,945,755 with Prime Factorization
| 5 | 719, 728, 805, 945, 755 |
| 7 | 719, 728, 161, 189, 151 |
| 719, 104, 23, 27, 151 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 719 x 104 x 23 x 27 x 151 = 245413710360
Therefore, the lowest common multiple of 719,728,805,945,755 is 245413710360.
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.
719 x 728 x 805 x 945 x 755 = 300631795191000
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.
719 : 1, 719
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
805 : 1, 5, 7, 23, 35, 115, 161, 805
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,728,805,945,755, is 1.
Now, the common factors can be found like this.
719:719
728:2x 2x 2x 7x 13
805:5x 7x 23
945:3x 3x 3x 5x 7
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 7 = 1225
Therefore, the value for common factors is 1225.
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 = 300631795191000/(1x1225)
LCM = 300631795191000/1225
LCM = 245413710360
Thus, we can understand that the LCM of 719,728,805,945,755 is 245413710360.
