Given numbers are 157,497,560,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,497,560,868 is 193511920.
Find LCM of 157,497,560,868 with Prime Factorization
2 | 157, 497, 560, 868 |
2 | 157, 497, 280, 434 |
7 | 157, 497, 140, 217 |
157, 71, 20, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 157 x 71 x 20 x 31 = 193511920
Therefore, the lowest common multiple of 157,497,560,868 is 193511920.
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.
157 x 497 x 560 x 868 = 37928336320
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.
157 : 1, 157
497 : 1, 7, 71, 497
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,497,560,868, is 1.
Now, the common factors can be found like this.
157:157
497:7x 71
560:2x 2x 2x 2x 5x 7
868:2x 2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 37928336320/(1x196)
LCM = 37928336320/196
LCM = 193511920
Thus, we can understand that the LCM of 157,497,560,868 is 193511920.
