Given numbers are 172,660,501,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,660,501,756 is 298585980.
Find LCM of 172,660,501,756 with Prime Factorization
| 2 | 172, 660, 501, 756 |
| 2 | 86, 330, 501, 378 |
| 3 | 43, 165, 501, 189 |
| 43, 55, 167, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 55 x 167 x 63 = 298585980
Therefore, the lowest common multiple of 172,660,501,756 is 298585980.
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.
172 x 660 x 501 x 756 = 42996381120
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.
172 : 1, 2, 4, 43, 86, 172
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
501 : 1, 3, 167, 501
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,660,501,756, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
660:2x 2x 3x 5x 11
501:3x 167
756:2x 2x 3x 3x 3x 7
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 = 42996381120/(1x144)
LCM = 42996381120/144
LCM = 298585980
Thus, we can understand that the LCM of 172,660,501,756 is 298585980.
