Given numbers are 620,365,990,803,508
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,365,990,803,508 is 569053980.
Find LCM of 620,365,990,803,508 with Prime Factorization
| 2 | 620, 365, 990, 803, 508 |
| 2 | 310, 365, 495, 803, 254 |
| 5 | 155, 365, 495, 803, 127 |
| 11 | 31, 73, 99, 803, 127 |
| 73 | 31, 73, 9, 73, 127 |
| 31, 1, 9, 1, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 73 x 31 x 1 x 9 x 1 x 127 = 569053980
Therefore, the lowest common multiple of 620,365,990,803,508 is 569053980.
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 365 x 990 x 803 x 508 = 91390069188000
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
365 : 1, 5, 73, 365
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
803 : 1, 11, 73, 803
508 : 1, 2, 4, 127, 254, 508
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,365,990,803,508, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
365:5x 73
990:2x 3x 3x 5x 11
803:11x 73
508:2x 2x 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 2x 5x 5x 11x 73 = 160600
Therefore, the value for common factors is 160600.
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 = 91390069188000/(1x160600)
LCM = 91390069188000/160600
LCM = 569053980
Thus, we can understand that the LCM of 620,365,990,803,508 is 569053980.
