Given numbers are 977,561,695,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,561,695,901 is 20189152995.
Find LCM of 977,561,695,901 with Prime Factorization
| 17 | 977, 561, 695, 901 |
| 977, 33, 695, 53 |
Multiply the prime numbers at the bottom and the left side.
17 x 977 x 33 x 695 x 53 = 20189152995
Therefore, the lowest common multiple of 977,561,695,901 is 20189152995.
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.
977 x 561 x 695 x 901 = 343215600915
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.
977 : 1, 977
561 : 1, 3, 11, 17, 33, 51, 187, 561
695 : 1, 5, 139, 695
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,561,695,901, is 1.
Now, the common factors can be found like this.
977:977
561:3x 11x 17
695:5x 139
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.
17 = 17
Therefore, the value for common factors is 17.
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 = 343215600915/(1x17)
LCM = 343215600915/17
LCM = 20189152995
Thus, we can understand that the LCM of 977,561,695,901 is 20189152995.
