Given numbers are 909,735,286,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,735,286,140 is 127387260.
Find LCM of 909,735,286,140 with Prime Factorization
| 2 | 909, 735, 286, 140 |
| 3 | 909, 735, 143, 70 |
| 5 | 303, 245, 143, 70 |
| 7 | 303, 49, 143, 14 |
| 303, 7, 143, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 303 x 7 x 143 x 2 = 127387260
Therefore, the lowest common multiple of 909,735,286,140 is 127387260.
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.
909 x 735 x 286 x 140 = 26751324600
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.
909 : 1, 3, 9, 101, 303, 909
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
286 : 1, 2, 11, 13, 22, 26, 143, 286
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,735,286,140, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
735:3x 5x 7x 7
286:2x 11x 13
140:2x 2x 5x 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 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 26751324600/(1x210)
LCM = 26751324600/210
LCM = 127387260
Thus, we can understand that the LCM of 909,735,286,140 is 127387260.
