Find LCM of 476,639,675,680 with Prime Factorization
| 2 | 476, 639, 675, 680 |
| 2 | 238, 639, 675, 340 |
| 3 | 119, 639, 675, 170 |
| 3 | 119, 213, 225, 170 |
| 5 | 119, 71, 75, 170 |
| 17 | 119, 71, 15, 34 |
| 7, 71, 15, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 17 x 7 x 71 x 15 x 2 = 45624600
Therefore, the lowest common multiple of 476,639,675,680 is 45624600.
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.
476 x 639 x 675 x 680 = 139611276000
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
639 : 1, 3, 9, 71, 213, 639
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,639,675,680, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
639:3x 3x 71
675:3x 3x 3x 5x 5
680:2x 2x 2x 5x 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 3x 3x 5x 17 = 3060
Therefore, the value for common factors is 3060.
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 = 139611276000/(1x3060)
LCM = 139611276000/3060
LCM = 45624600
Thus, we can understand that the LCM of 476,639,675,680 is 45624600.
