Find LCM of 974,320,128,895 with Prime Factorization
| 2 | 974, 320, 128, 895 |
| 2 | 487, 160, 64, 895 |
| 2 | 487, 80, 32, 895 |
| 2 | 487, 40, 16, 895 |
| 2 | 487, 20, 8, 895 |
| 2 | 487, 10, 4, 895 |
| 5 | 487, 5, 2, 895 |
| 487, 1, 2, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 5 x 487 x 1 x 2 x 179 = 55790720
Therefore, the lowest common multiple of 974,320,128,895 is 55790720.
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.
974 x 320 x 128 x 895 = 35706060800
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.
974 : 1, 2, 487, 974
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
128 : 1, 2, 4, 8, 16, 32, 64, 128
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,320,128,895, is 1.
Now, the common factors can be found like this.
974:2x 487
320:2x 2x 2x 2x 2x 2x 5
128:2x 2x 2x 2x 2x 2x 2
895:5x 179
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 5 = 640
Therefore, the value for common factors is 640.
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 = 35706060800/(1x640)
LCM = 35706060800/640
LCM = 55790720
Thus, we can understand that the LCM of 974,320,128,895 is 55790720.
