Find LCM of 157,613,897,750,390 with Prime Factorization
| 2 | 157, 613, 897, 750, 390 |
| 3 | 157, 613, 897, 375, 195 |
| 5 | 157, 613, 299, 125, 65 |
| 13 | 157, 613, 299, 25, 13 |
| 157, 613, 23, 25, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 157 x 613 x 23 x 25 x 1 = 21582044250
Therefore, the lowest common multiple of 157,613,897,750,390 is 21582044250.
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.
157 x 613 x 897 x 750 x 390 = 25250991772500
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.
157 : 1, 157
613 : 1, 613
897 : 1, 3, 13, 23, 39, 69, 299, 897
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,613,897,750,390, is 1.
Now, the common factors can be found like this.
157:157
613:613
897:3x 13x 23
750:2x 3x 5x 5x 5
390:2x 3x 5x 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 3x 3x 5x 13 = 1170
Therefore, the value for common factors is 1170.
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 = 25250991772500/(1x1170)
LCM = 25250991772500/1170
LCM = 21582044250
Thus, we can understand that the LCM of 157,613,897,750,390 is 21582044250.
