Find LCM of 812,989,221,254,468 with Prime Factorization
| 2 | 812, 989, 221, 254, 468 |
| 2 | 406, 989, 221, 127, 234 |
| 13 | 203, 989, 221, 127, 117 |
| 203, 989, 17, 127, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 203 x 989 x 17 x 127 x 9 = 202857386004
Therefore, the lowest common multiple of 812,989,221,254,468 is 202857386004.
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.
812 x 989 x 221 x 254 x 468 = 21097168144416
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
989 : 1, 23, 43, 989
221 : 1, 13, 17, 221
254 : 1, 2, 127, 254
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,989,221,254,468, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
989:23x 43
221:13x 17
254:2x 127
468:2x 2x 3x 3x 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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 21097168144416/(1x104)
LCM = 21097168144416/104
LCM = 202857386004
Thus, we can understand that the LCM of 812,989,221,254,468 is 202857386004.
