Given numbers are 546,947,909,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,947,909,947 is 156669786.
Find LCM of 546,947,909,947 with Prime Factorization
| 3 | 546, 947, 909, 947 |
| 947 | 182, 947, 303, 947 |
| 182, 1, 303, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 947 x 182 x 1 x 303 x 1 = 156669786
Therefore, the lowest common multiple of 546,947,909,947 is 156669786.
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.
546 x 947 x 909 x 947 = 445098862026
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
947 : 1, 947
909 : 1, 3, 9, 101, 303, 909
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,947,909,947, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
947:947
909:3x 3x 101
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 947 = 2841
Therefore, the value for common factors is 2841.
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 = 445098862026/(1x2841)
LCM = 445098862026/2841
LCM = 156669786
Thus, we can understand that the LCM of 546,947,909,947 is 156669786.
