Find LCM of 545,404,672,717,620 with Prime Factorization
| 2 | 545, 404, 672, 717, 620 |
| 2 | 545, 202, 336, 717, 310 |
| 3 | 545, 101, 168, 717, 155 |
| 5 | 545, 101, 56, 239, 155 |
| 109, 101, 56, 239, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 109 x 101 x 56 x 239 x 31 = 274060688160
Therefore, the lowest common multiple of 545,404,672,717,620 is 274060688160.
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.
545 x 404 x 672 x 717 x 620 = 65774565158400
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.
545 : 1, 5, 109, 545
404 : 1, 2, 4, 101, 202, 404
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
717 : 1, 3, 239, 717
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,404,672,717,620, is 1.
Now, the common factors can be found like this.
545:5x 109
404:2x 2x 101
672:2x 2x 2x 2x 2x 3x 7
717:3x 239
620:2x 2x 5x 31
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 65774565158400/(1x240)
LCM = 65774565158400/240
LCM = 274060688160
Thus, we can understand that the LCM of 545,404,672,717,620 is 274060688160.
