Given numbers are 628,776,693,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,776,693,612 is 1435302792.
Find LCM of 628,776,693,612 with Prime Factorization
| 2 | 628, 776, 693, 612 |
| 2 | 314, 388, 693, 306 |
| 3 | 157, 194, 693, 153 |
| 3 | 157, 194, 231, 51 |
| 157, 194, 77, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 157 x 194 x 77 x 17 = 1435302792
Therefore, the lowest common multiple of 628,776,693,612 is 1435302792.
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.
628 x 776 x 693 x 612 = 206683602048
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.
628 : 1, 2, 4, 157, 314, 628
776 : 1, 2, 4, 8, 97, 194, 388, 776
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,776,693,612, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
776:2x 2x 2x 97
693:3x 3x 7x 11
612:2x 2x 3x 3x 17
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 206683602048/(1x144)
LCM = 206683602048/144
LCM = 1435302792
Thus, we can understand that the LCM of 628,776,693,612 is 1435302792.
