Given numbers are 637,203,117,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,203,117,247 is 3158883.
Find LCM of 637,203,117,247 with Prime Factorization
| 7 | 637, 203, 117, 247 |
| 13 | 91, 29, 117, 247 |
| 7, 29, 9, 19 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 7 x 29 x 9 x 19 = 3158883
Therefore, the lowest common multiple of 637,203,117,247 is 3158883.
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.
637 x 203 x 117 x 247 = 3736958589
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.
637 : 1, 7, 13, 49, 91, 637
203 : 1, 7, 29, 203
117 : 1, 3, 9, 13, 39, 117
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,203,117,247, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
203:7x 29
117:3x 3x 13
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 13 = 1183
Therefore, the value for common factors is 1183.
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 = 3736958589/(1x1183)
LCM = 3736958589/1183
LCM = 3158883
Thus, we can understand that the LCM of 637,203,117,247 is 3158883.
