Given numbers are 642,981,432,935,167
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,981,432,935,167 is 786723466320.
Find LCM of 642,981,432,935,167 with Prime Factorization
| 2 | 642, 981, 432, 935, 167 |
| 3 | 321, 981, 216, 935, 167 |
| 3 | 107, 327, 72, 935, 167 |
| 107, 109, 24, 935, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 107 x 109 x 24 x 935 x 167 = 786723466320
Therefore, the lowest common multiple of 642,981,432,935,167 is 786723466320.
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.
642 x 981 x 432 x 935 x 167 = 42483067181280
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
981 : 1, 3, 9, 109, 327, 981
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
935 : 1, 5, 11, 17, 55, 85, 187, 935
167 : 1, 167
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,981,432,935,167, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
981:3x 3x 109
432:2x 2x 2x 2x 3x 3x 3
935:5x 11x 17
167:167
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 3 = 54
Therefore, the value for common factors is 54.
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 = 42483067181280/(1x54)
LCM = 42483067181280/54
LCM = 786723466320
Thus, we can understand that the LCM of 642,981,432,935,167 is 786723466320.
