The LCM of 455,200,989,572 is 197997800.
Find LCM of 455,200,989,572 with Prime Factorization
| 2 | 455, 200, 989, 572 |
| 2 | 455, 100, 989, 286 |
| 5 | 455, 50, 989, 143 |
| 13 | 91, 10, 989, 143 |
| 7, 10, 989, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 7 x 10 x 989 x 11 = 197997800
Therefore, the lowest common multiple of 455,200,989,572 is 197997800.
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.
455 x 200 x 989 x 572 = 51479428000
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
989 : 1, 23, 43, 989
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,200,989,572, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
200:2x 2x 2x 5x 5
989:23x 43
572:2x 2x 11x 13
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 13 = 260
Therefore, the value for common factors is 260.
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 = 51479428000/(1x260)
LCM = 51479428000/260
LCM = 197997800
Thus, we can understand that the LCM of 455,200,989,572 is 197997800.
