Given numbers are 275,628,620,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 275,628,620,381 is 2039759700.
Find LCM of 275,628,620,381 with Prime Factorization
| 2 | 275, 628, 620, 381 |
| 2 | 275, 314, 310, 381 |
| 5 | 275, 157, 155, 381 |
| 55, 157, 31, 381 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 55 x 157 x 31 x 381 = 2039759700
Therefore, the lowest common multiple of 275,628,620,381 is 2039759700.
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.
275 x 628 x 620 x 381 = 40795194000
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.
275 : 1, 5, 11, 25, 55, 275
628 : 1, 2, 4, 157, 314, 628
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,628,620,381, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
628:2x 2x 157
620:2x 2x 5x 31
381:3x 127
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 5 = 20
Therefore, the value for common factors is 20.
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 = 40795194000/(1x20)
LCM = 40795194000/20
LCM = 2039759700
Thus, we can understand that the LCM of 275,628,620,381 is 2039759700.
