Find LCM of 570,760,638,705,798 with Prime Factorization
| 2 | 570, 760, 638, 705, 798 |
| 3 | 285, 380, 319, 705, 399 |
| 5 | 95, 380, 319, 235, 133 |
| 19 | 19, 76, 319, 47, 133 |
| 1, 4, 319, 47, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 4 x 319 x 47 x 7 = 239288280
Therefore, the lowest common multiple of 570,760,638,705,798 is 239288280.
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.
570 x 760 x 638 x 705 x 798 = 155489524344000
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
638 : 1, 2, 11, 22, 29, 58, 319, 638
705 : 1, 3, 5, 15, 47, 141, 235, 705
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,760,638,705,798, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
760:2x 2x 2x 5x 19
638:2x 11x 29
705:3x 5x 47
798:2x 3x 7x 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 3x 3x 5x 5x 19x 19 = 649800
Therefore, the value for common factors is 649800.
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 = 155489524344000/(1x649800)
LCM = 155489524344000/649800
LCM = 239288280
Thus, we can understand that the LCM of 570,760,638,705,798 is 239288280.
