Given numbers are 977,393,131,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,393,131,747 is 95606289.
Find LCM of 977,393,131,747 with Prime Factorization
| 3 | 977, 393, 131, 747 |
| 131 | 977, 131, 131, 249 |
| 977, 1, 1, 249 |
Multiply the prime numbers at the bottom and the left side.
3 x 131 x 977 x 1 x 1 x 249 = 95606289
Therefore, the lowest common multiple of 977,393,131,747 is 95606289.
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 393 x 131 x 747 = 37573271577
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
393 : 1, 3, 131, 393
131 : 1, 131
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,393,131,747, is 1.
Now, the common factors can be found like this.
977:977
393:3x 131
131:131
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 131 = 393
Therefore, the value for common factors is 393.
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 = 37573271577/(1x393)
LCM = 37573271577/393
LCM = 95606289
Thus, we can understand that the LCM of 977,393,131,747 is 95606289.
