Given numbers are 981,143,570,967
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,143,570,967 is 25774195590.
Find LCM of 981,143,570,967 with Prime Factorization
| 3 | 981, 143, 570, 967 |
| 327, 143, 190, 967 |
Multiply the prime numbers at the bottom and the left side.
3 x 327 x 143 x 190 x 967 = 25774195590
Therefore, the lowest common multiple of 981,143,570,967 is 25774195590.
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.
981 x 143 x 570 x 967 = 77322586770
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.
981 : 1, 3, 9, 109, 327, 981
143 : 1, 11, 13, 143
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
967 : 1, 967
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,143,570,967, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
143:11x 13
570:2x 3x 5x 19
967:967
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 77322586770/(1x3)
LCM = 77322586770/3
LCM = 25774195590
Thus, we can understand that the LCM of 981,143,570,967 is 25774195590.
