Given numbers are 990,722,502,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,722,502,722 is 89704890.
Find LCM of 990,722,502,722 with Prime Factorization
| 2 | 990, 722, 502, 722 |
| 19 | 495, 361, 251, 361 |
| 19 | 495, 19, 251, 19 |
| 495, 1, 251, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 19 x 495 x 1 x 251 x 1 = 89704890
Therefore, the lowest common multiple of 990,722,502,722 is 89704890.
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.
990 x 722 x 502 x 722 = 259067722320
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.
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
722 : 1, 2, 19, 38, 361, 722
502 : 1, 2, 251, 502
722 : 1, 2, 19, 38, 361, 722
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,722,502,722, is 2.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
722:2x 19x 19
502:2x 251
722:2x 19x 19
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 19x 19 = 1444
Therefore, the value for common factors is 1444.
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 = 259067722320/(2x1444)
LCM = 259067722320/2888
LCM = 89704890
Thus, we can understand that the LCM of 990,722,502,722 is 89704890.
