Find LCM of 441,116,168,640,988 with Prime Factorization
| 2 | 441, 116, 168, 640, 988 |
| 2 | 441, 58, 84, 320, 494 |
| 2 | 441, 29, 42, 160, 247 |
| 3 | 441, 29, 21, 80, 247 |
| 7 | 147, 29, 7, 80, 247 |
| 21, 29, 1, 80, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 21 x 29 x 1 x 80 x 247 = 2021685120
Therefore, the lowest common multiple of 441,116,168,640,988 is 2021685120.
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.
441 x 116 x 168 x 640 x 988 = 5434289602560
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
116 : 1, 2, 4, 29, 58, 116
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,116,168,640,988, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
116:2x 2x 29
168:2x 2x 2x 3x 7
640:2x 2x 2x 2x 2x 2x 2x 5
988:2x 2x 13x 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 2x 2x 2x 2x 2x 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 5434289602560/(1x2688)
LCM = 5434289602560/2688
LCM = 2021685120
Thus, we can understand that the LCM of 441,116,168,640,988 is 2021685120.
