Find LCM of 782,171,807,748,387 with Prime Factorization
| 2 | 782, 171, 807, 748, 387 |
| 3 | 391, 171, 807, 374, 387 |
| 3 | 391, 57, 269, 374, 129 |
| 17 | 391, 19, 269, 374, 43 |
| 23, 19, 269, 22, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 23 x 19 x 269 x 22 x 43 = 34028772228
Therefore, the lowest common multiple of 782,171,807,748,387 is 34028772228.
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.
782 x 171 x 807 x 748 x 387 = 31238412905304
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
171 : 1, 3, 9, 19, 57, 171
807 : 1, 3, 269, 807
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,171,807,748,387, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
171:3x 3x 19
807:3x 269
748:2x 2x 11x 17
387:3x 3x 43
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 3x 17 = 918
Therefore, the value for common factors is 918.
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 = 31238412905304/(1x918)
LCM = 31238412905304/918
LCM = 34028772228
Thus, we can understand that the LCM of 782,171,807,748,387 is 34028772228.
