Given numbers are 620,206,353,361,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,206,353,361,890 is 724270552820.
Find LCM of 620,206,353,361,890 with Prime Factorization
2 | 620, 206, 353, 361, 890 |
5 | 310, 103, 353, 361, 445 |
62, 103, 353, 361, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 62 x 103 x 353 x 361 x 89 = 724270552820
Therefore, the lowest common multiple of 620,206,353,361,890 is 724270552820.
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 206 x 353 x 361 x 890 = 14485411056400
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
206 : 1, 2, 103, 206
353 : 1, 353
361 : 1, 19, 361
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,206,353,361,890, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
206:2x 103
353:353
361:19x 19
890:2x 5x 89
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 = 14485411056400/(1x20)
LCM = 14485411056400/20
LCM = 724270552820
Thus, we can understand that the LCM of 620,206,353,361,890 is 724270552820.
