Given numbers are 874,155,561,713
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,155,561,713 is 75998670.
Find LCM of 874,155,561,713 with Prime Factorization
| 23 | 874, 155, 561, 713 |
| 31 | 38, 155, 561, 31 |
| 38, 5, 561, 1 |
Multiply the prime numbers at the bottom and the left side.
23 x 31 x 38 x 5 x 561 x 1 = 75998670
Therefore, the lowest common multiple of 874,155,561,713 is 75998670.
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.
874 x 155 x 561 x 713 = 54187051710
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
155 : 1, 5, 31, 155
561 : 1, 3, 11, 17, 33, 51, 187, 561
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,155,561,713, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
155:5x 31
561:3x 11x 17
713:23x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 31 = 713
Therefore, the value for common factors is 713.
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 = 54187051710/(1x713)
LCM = 54187051710/713
LCM = 75998670
Thus, we can understand that the LCM of 874,155,561,713 is 75998670.
