Given numbers are 628,170,520,794,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,170,520,794,102 is 1652965080.
Find LCM of 628,170,520,794,102 with Prime Factorization
| 2 | 628, 170, 520, 794, 102 |
| 2 | 314, 85, 260, 397, 51 |
| 5 | 157, 85, 130, 397, 51 |
| 17 | 157, 17, 26, 397, 51 |
| 157, 1, 26, 397, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 157 x 1 x 26 x 397 x 3 = 1652965080
Therefore, the lowest common multiple of 628,170,520,794,102 is 1652965080.
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 170 x 520 x 794 x 102 = 4496065017600
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
794 : 1, 2, 397, 794
102 : 1, 2, 3, 6, 17, 34, 51, 102
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,170,520,794,102, is 2.
Now, the common factors can be found like this.
628:2x 2x 157
170:2x 5x 17
520:2x 2x 2x 5x 13
794:2x 397
102:2x 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 5x 17 = 1360
Therefore, the value for common factors is 1360.
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 = 4496065017600/(2x1360)
LCM = 4496065017600/2720
LCM = 1652965080
Thus, we can understand that the LCM of 628,170,520,794,102 is 1652965080.
