Given numbers are 901,909,170,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,909,170,740 is 606066660.
Find LCM of 901,909,170,740 with Prime Factorization
| 2 | 901, 909, 170, 740 |
| 5 | 901, 909, 85, 370 |
| 17 | 901, 909, 17, 74 |
| 53, 909, 1, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 53 x 909 x 1 x 74 = 606066660
Therefore, the lowest common multiple of 901,909,170,740 is 606066660.
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.
901 x 909 x 170 x 740 = 103031332200
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.
901 : 1, 17, 53, 901
909 : 1, 3, 9, 101, 303, 909
170 : 1, 2, 5, 10, 17, 34, 85, 170
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,909,170,740, is 1.
Now, the common factors can be found like this.
901:17x 53
909:3x 3x 101
170:2x 5x 17
740:2x 2x 5x 37
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 17 = 170
Therefore, the value for common factors is 170.
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 = 103031332200/(1x170)
LCM = 103031332200/170
LCM = 606066660
Thus, we can understand that the LCM of 901,909,170,740 is 606066660.
