Given numbers are 890,666,629,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,666,629,620 is 312373980.
Find LCM of 890,666,629,620 with Prime Factorization
| 2 | 890, 666, 629, 620 |
| 5 | 445, 333, 629, 310 |
| 37 | 89, 333, 629, 62 |
| 89, 9, 17, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 37 x 89 x 9 x 17 x 62 = 312373980
Therefore, the lowest common multiple of 890,666,629,620 is 312373980.
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.
890 x 666 x 629 x 620 = 231156745200
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
629 : 1, 17, 37, 629
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 890,666,629,620, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
666:2x 3x 3x 37
629:17x 37
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 5x 37 = 740
Therefore, the value for common factors is 740.
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 = 231156745200/(1x740)
LCM = 231156745200/740
LCM = 312373980
Thus, we can understand that the LCM of 890,666,629,620 is 312373980.
