Find LCM of 651,165,981,374,728 with Prime Factorization
2 | 651, 165, 981, 374, 728 |
3 | 651, 165, 981, 187, 364 |
7 | 217, 55, 327, 187, 364 |
11 | 31, 55, 327, 187, 52 |
31, 5, 327, 17, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 31 x 5 x 327 x 17 x 52 = 20700159480
Therefore, the lowest common multiple of 651,165,981,374,728 is 20700159480.
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.
651 x 165 x 981 x 374 x 728 = 28690421039280
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
165 : 1, 3, 5, 11, 15, 33, 55, 165
981 : 1, 3, 9, 109, 327, 981
374 : 1, 2, 11, 17, 22, 34, 187, 374
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,165,981,374,728, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
165:3x 5x 11
981:3x 3x 109
374:2x 11x 17
728:2x 2x 2x 7x 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 7x 11 = 1386
Therefore, the value for common factors is 1386.
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 = 28690421039280/(1x1386)
LCM = 28690421039280/1386
LCM = 20700159480
Thus, we can understand that the LCM of 651,165,981,374,728 is 20700159480.
