Find LCM of 730,770,390,190,693 with Prime Factorization
| 2 | 730, 770, 390, 190, 693 |
| 3 | 365, 385, 195, 95, 693 |
| 5 | 365, 385, 65, 95, 231 |
| 7 | 73, 77, 13, 19, 231 |
| 11 | 73, 11, 13, 19, 33 |
| 73, 1, 13, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 73 x 1 x 13 x 19 x 3 = 124954830
Therefore, the lowest common multiple of 730,770,390,190,693 is 124954830.
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.
730 x 770 x 390 x 190 x 693 = 28864565730000
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
190 : 1, 2, 5, 10, 19, 38, 95, 190
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,770,390,190,693, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
770:2x 5x 7x 11
390:2x 3x 5x 13
190:2x 5x 19
693:3x 3x 7x 11
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 5x 5x 7x 11 = 231000
Therefore, the value for common factors is 231000.
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 = 28864565730000/(1x231000)
LCM = 28864565730000/231000
LCM = 124954830
Thus, we can understand that the LCM of 730,770,390,190,693 is 124954830.
