Given numbers are 655,385,638,269,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,385,638,269,154 is 786886870.
Find LCM of 655,385,638,269,154 with Prime Factorization
| 2 | 655, 385, 638, 269, 154 |
| 5 | 655, 385, 319, 269, 77 |
| 7 | 131, 77, 319, 269, 77 |
| 11 | 131, 11, 319, 269, 11 |
| 131, 1, 29, 269, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 131 x 1 x 29 x 269 x 1 = 786886870
Therefore, the lowest common multiple of 655,385,638,269,154 is 786886870.
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.
655 x 385 x 638 x 269 x 154 = 6664931788900
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.
655 : 1, 5, 131, 655
385 : 1, 5, 7, 11, 35, 55, 77, 385
638 : 1, 2, 11, 22, 29, 58, 319, 638
269 : 1, 269
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,385,638,269,154, is 1.
Now, the common factors can be found like this.
655:5x 131
385:5x 7x 11
638:2x 11x 29
269:269
154:2x 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 5x 7x 11x 11 = 8470
Therefore, the value for common factors is 8470.
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 = 6664931788900/(1x8470)
LCM = 6664931788900/8470
LCM = 786886870
Thus, we can understand that the LCM of 655,385,638,269,154 is 786886870.
