Given numbers are 277,140,406,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 277,140,406,308 is 12370820.
Find LCM of 277,140,406,308 with Prime Factorization
| 2 | 277, 140, 406, 308 |
| 2 | 277, 70, 203, 154 |
| 7 | 277, 35, 203, 77 |
| 277, 5, 29, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 277 x 5 x 29 x 11 = 12370820
Therefore, the lowest common multiple of 277,140,406,308 is 12370820.
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.
277 x 140 x 406 x 308 = 4849361440
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.
277 : 1, 277
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
406 : 1, 2, 7, 14, 29, 58, 203, 406
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,140,406,308, is 1.
Now, the common factors can be found like this.
277:277
140:2x 2x 5x 7
406:2x 7x 29
308:2x 2x 7x 11
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 4849361440/(1x392)
LCM = 4849361440/392
LCM = 12370820
Thus, we can understand that the LCM of 277,140,406,308 is 12370820.
