Find LCM of 868,174,640,960,278 with Prime Factorization
| 2 | 868, 174, 640, 960, 278 |
| 2 | 434, 87, 320, 480, 139 |
| 2 | 217, 87, 160, 240, 139 |
| 2 | 217, 87, 80, 120, 139 |
| 2 | 217, 87, 40, 60, 139 |
| 2 | 217, 87, 20, 30, 139 |
| 3 | 217, 87, 10, 15, 139 |
| 5 | 217, 29, 10, 5, 139 |
| 217, 29, 2, 1, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 217 x 29 x 2 x 1 x 139 = 1679475840
Therefore, the lowest common multiple of 868,174,640,960,278 is 1679475840.
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.
868 x 174 x 640 x 960 x 278 = 25796748902400
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
174 : 1, 2, 3, 6, 29, 58, 87, 174
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
278 : 1, 2, 139, 278
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,174,640,960,278, is 2.
Now, the common factors can be found like this.
868:2x 2x 7x 31
174:2x 3x 29
640:2x 2x 2x 2x 2x 2x 2x 5
960:2x 2x 2x 2x 2x 2x 3x 5
278:2x 139
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 5 = 7680
Therefore, the value for common factors is 7680.
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 = 25796748902400/(2x7680)
LCM = 25796748902400/15360
LCM = 1679475840
Thus, we can understand that the LCM of 868,174,640,960,278 is 1679475840.
