Find LCM of 616,575,306,840 with Prime Factorization
| 2 | 616, 575, 306, 840 |
| 2 | 308, 575, 153, 420 |
| 2 | 154, 575, 153, 210 |
| 3 | 77, 575, 153, 105 |
| 5 | 77, 575, 51, 35 |
| 7 | 77, 115, 51, 7 |
| 11, 115, 51, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 11 x 115 x 51 x 1 = 54192600
Therefore, the lowest common multiple of 616,575,306,840 is 54192600.
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.
616 x 575 x 306 x 840 = 91043568000
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
575 : 1, 5, 23, 25, 115, 575
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,575,306,840, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
575:5x 5x 23
306:2x 3x 3x 17
840:2x 2x 2x 3x 5x 7
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 3x 5x 7 = 1680
Therefore, the value for common factors is 1680.
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 = 91043568000/(1x1680)
LCM = 91043568000/1680
LCM = 54192600
Thus, we can understand that the LCM of 616,575,306,840 is 54192600.
