Find LCM of 172,240,284,473,570 with Prime Factorization
| 2 | 172, 240, 284, 473, 570 |
| 2 | 86, 120, 142, 473, 285 |
| 3 | 43, 60, 71, 473, 285 |
| 5 | 43, 20, 71, 473, 95 |
| 43 | 43, 4, 71, 473, 19 |
| 1, 4, 71, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 1 x 4 x 71 x 11 x 19 = 153138480
Therefore, the lowest common multiple of 172,240,284,473,570 is 153138480.
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.
172 x 240 x 284 x 473 x 570 = 3160778227200
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.
172 : 1, 2, 4, 43, 86, 172
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
284 : 1, 2, 4, 71, 142, 284
473 : 1, 11, 43, 473
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,240,284,473,570, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
240:2x 2x 2x 2x 3x 5
284:2x 2x 71
473:11x 43
570:2x 3x 5x 19
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 3x 5x 43 = 20640
Therefore, the value for common factors is 20640.
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 = 3160778227200/(1x20640)
LCM = 3160778227200/20640
LCM = 153138480
Thus, we can understand that the LCM of 172,240,284,473,570 is 153138480.
