Given numbers are 752,120,965,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 752,120,965,728 is 198110640.
Find LCM of 752,120,965,728 with Prime Factorization
| 2 | 752, 120, 965, 728 |
| 2 | 376, 60, 965, 364 |
| 2 | 188, 30, 965, 182 |
| 5 | 94, 15, 965, 91 |
| 94, 3, 193, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 94 x 3 x 193 x 91 = 198110640
Therefore, the lowest common multiple of 752,120,965,728 is 198110640.
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.
752 x 120 x 965 x 728 = 63395404800
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.
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
965 : 1, 5, 193, 965
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 752,120,965,728, is 1.
Now, the common factors can be found like this.
752:2x 2x 2x 2x 47
120:2x 2x 2x 3x 5
965:5x 193
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 2x 2x 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 63395404800/(1x320)
LCM = 63395404800/320
LCM = 198110640
Thus, we can understand that the LCM of 752,120,965,728 is 198110640.
