Given numbers are 620,890,802,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,890,802,217 is 154890260.
Find LCM of 620,890,802,217 with Prime Factorization
| 2 | 620, 890, 802, 217 |
| 5 | 310, 445, 401, 217 |
| 31 | 62, 89, 401, 217 |
| 2, 89, 401, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 2 x 89 x 401 x 7 = 154890260
Therefore, the lowest common multiple of 620,890,802,217 is 154890260.
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.
620 x 890 x 802 x 217 = 96031961200
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
890 : 1, 2, 5, 10, 89, 178, 445, 890
802 : 1, 2, 401, 802
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,890,802,217, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
890:2x 5x 89
802:2x 401
217:7x 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 31 = 620
Therefore, the value for common factors is 620.
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 = 96031961200/(1x620)
LCM = 96031961200/620
LCM = 154890260
Thus, we can understand that the LCM of 620,890,802,217 is 154890260.
