Find LCM of 812,847,790,371,945 with Prime Factorization
| 2 | 812, 847, 790, 371, 945 |
| 5 | 406, 847, 395, 371, 945 |
| 7 | 406, 847, 79, 371, 189 |
| 58, 121, 79, 53, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 58 x 121 x 79 x 53 x 27 = 55536451740
Therefore, the lowest common multiple of 812,847,790,371,945 is 55536451740.
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.
812 x 847 x 790 x 371 x 945 = 190490029468200
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
847 : 1, 7, 11, 77, 121, 847
790 : 1, 2, 5, 10, 79, 158, 395, 790
371 : 1, 7, 53, 371
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,847,790,371,945, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
847:7x 11x 11
790:2x 5x 79
371:7x 53
945:3x 3x 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 5x 7x 7x 7 = 3430
Therefore, the value for common factors is 3430.
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 = 190490029468200/(1x3430)
LCM = 190490029468200/3430
LCM = 55536451740
Thus, we can understand that the LCM of 812,847,790,371,945 is 55536451740.
