Given numbers are 775,735,350,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,735,350,728 is 11848200.
Find LCM of 775,735,350,728 with Prime Factorization
| 2 | 775, 735, 350, 728 |
| 5 | 775, 735, 175, 364 |
| 5 | 155, 147, 35, 364 |
| 7 | 31, 147, 7, 364 |
| 31, 21, 1, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 7 x 31 x 21 x 1 x 52 = 11848200
Therefore, the lowest common multiple of 775,735,350,728 is 11848200.
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.
775 x 735 x 350 x 728 = 145140450000
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.
775 : 1, 5, 25, 31, 155, 775
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,735,350,728, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
735:3x 5x 7x 7
350:2x 5x 5x 7
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5x 7x 7 = 12250
Therefore, the value for common factors is 12250.
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 = 145140450000/(1x12250)
LCM = 145140450000/12250
LCM = 11848200
Thus, we can understand that the LCM of 775,735,350,728 is 11848200.
