The LCM of 888,405,157,620 is 583455960.
Find LCM of 888,405,157,620 with Prime Factorization
| 2 | 888, 405, 157, 620 |
| 2 | 444, 405, 157, 310 |
| 3 | 222, 405, 157, 155 |
| 5 | 74, 135, 157, 155 |
| 74, 27, 157, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 74 x 27 x 157 x 31 = 583455960
Therefore, the lowest common multiple of 888,405,157,620 is 583455960.
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.
888 x 405 x 157 x 620 = 35007357600
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
157 : 1, 157
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,405,157,620, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
405:3x 3x 3x 3x 5
157:157
620:2x 2x 5x 31
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 35007357600/(1x60)
LCM = 35007357600/60
LCM = 583455960
Thus, we can understand that the LCM of 888,405,157,620 is 583455960.
