Find LCM of 781,560,195,764,234 with Prime Factorization
| 2 | 781, 560, 195, 764, 234 |
| 2 | 781, 280, 195, 382, 117 |
| 3 | 781, 140, 195, 191, 117 |
| 5 | 781, 140, 65, 191, 39 |
| 13 | 781, 28, 13, 191, 39 |
| 781, 28, 1, 191, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 781 x 28 x 1 x 191 x 3 = 9773683920
Therefore, the lowest common multiple of 781,560,195,764,234 is 9773683920.
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 560 x 195 x 764 x 234 = 15246946915200
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
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
195 : 1, 3, 5, 13, 15, 39, 65, 195
764 : 1, 2, 4, 191, 382, 764
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,560,195,764,234, is 1.
Now, the common factors can be found like this.
781:11x 71
560:2x 2x 2x 2x 5x 7
195:3x 5x 13
764:2x 2x 191
234:2x 3x 3x 13
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 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 15246946915200/(1x1560)
LCM = 15246946915200/1560
LCM = 9773683920
Thus, we can understand that the LCM of 781,560,195,764,234 is 9773683920.
