Find LCM of 672,640,436,476 with Prime Factorization
| 2 | 672, 640, 436, 476 |
| 2 | 336, 320, 218, 238 |
| 2 | 168, 160, 109, 119 |
| 2 | 84, 80, 109, 119 |
| 2 | 42, 40, 109, 119 |
| 7 | 21, 20, 109, 119 |
| 3, 20, 109, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 7 x 3 x 20 x 109 x 17 = 24904320
Therefore, the lowest common multiple of 672,640,436,476 is 24904320.
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.
672 x 640 x 436 x 476 = 89257082880
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.
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
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
436 : 1, 2, 4, 109, 218, 436
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,640,436,476, is 4.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
640:2x 2x 2x 2x 2x 2x 2x 5
436:2x 2x 109
476:2x 2x 7x 17
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 7 = 896
Therefore, the value for common factors is 896.
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 = 89257082880/(4x896)
LCM = 89257082880/3584
LCM = 24904320
Thus, we can understand that the LCM of 672,640,436,476 is 24904320.
