Find LCM of 228,640,916,669,672 with Prime Factorization
| 2 | 228, 640, 916, 669, 672 |
| 2 | 114, 320, 458, 669, 336 |
| 2 | 57, 160, 229, 669, 168 |
| 2 | 57, 80, 229, 669, 84 |
| 2 | 57, 40, 229, 669, 42 |
| 3 | 57, 20, 229, 669, 21 |
| 19, 20, 229, 223, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 19 x 20 x 229 x 223 x 7 = 13040469120
Therefore, the lowest common multiple of 228,640,916,669,672 is 13040469120.
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.
228 x 640 x 916 x 669 x 672 = 60090481704960
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
916 : 1, 2, 4, 229, 458, 916
669 : 1, 3, 223, 669
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,640,916,669,672, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
640:2x 2x 2x 2x 2x 2x 2x 5
916:2x 2x 229
669:3x 223
672:2x 2x 2x 2x 2x 3x 7
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 2x 2x 2x 2x 2x 2x 3x 3 = 4608
Therefore, the value for common factors is 4608.
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 = 60090481704960/(1x4608)
LCM = 60090481704960/4608
LCM = 13040469120
Thus, we can understand that the LCM of 228,640,916,669,672 is 13040469120.
