Given numbers are 988,187,871,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,187,871,901 is 656068556.
Find LCM of 988,187,871,901 with Prime Factorization
13 | 988, 187, 871, 901 |
17 | 76, 187, 67, 901 |
76, 11, 67, 53 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 76 x 11 x 67 x 53 = 656068556
Therefore, the lowest common multiple of 988,187,871,901 is 656068556.
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.
988 x 187 x 871 x 901 = 144991150876
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
187 : 1, 11, 17, 187
871 : 1, 13, 67, 871
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,187,871,901, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
187:11x 17
871:13x 67
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 144991150876/(1x221)
LCM = 144991150876/221
LCM = 656068556
Thus, we can understand that the LCM of 988,187,871,901 is 656068556.
