Find LCM of 781,717,220,475,600 with Prime Factorization
| 2 | 781, 717, 220, 475, 600 |
| 2 | 781, 717, 110, 475, 300 |
| 3 | 781, 717, 55, 475, 150 |
| 5 | 781, 239, 55, 475, 50 |
| 5 | 781, 239, 11, 95, 10 |
| 11 | 781, 239, 11, 19, 2 |
| 71, 239, 1, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 11 x 71 x 239 x 1 x 19 x 2 = 2127912600
Therefore, the lowest common multiple of 781,717,220,475,600 is 2127912600.
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.
781 x 717 x 220 x 475 x 600 = 35110557900000
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.
781 : 1, 11, 71, 781
717 : 1, 3, 239, 717
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
475 : 1, 5, 19, 25, 95, 475
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,717,220,475,600, is 1.
Now, the common factors can be found like this.
781:11x 71
717:3x 239
220:2x 2x 5x 11
475:5x 5x 19
600:2x 2x 2x 3x 5x 5
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 3x 5x 5x 5x 11 = 16500
Therefore, the value for common factors is 16500.
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 = 35110557900000/(1x16500)
LCM = 35110557900000/16500
LCM = 2127912600
Thus, we can understand that the LCM of 781,717,220,475,600 is 2127912600.
