Given numbers are 947,126,511,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,126,511,761 is 6628695066.
Find LCM of 947,126,511,761 with Prime Factorization
| 7 | 947, 126, 511, 761 |
| 947, 18, 73, 761 |
Multiply the prime numbers at the bottom and the left side.
7 x 947 x 18 x 73 x 761 = 6628695066
Therefore, the lowest common multiple of 947,126,511,761 is 6628695066.
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.
947 x 126 x 511 x 761 = 46400865462
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.
947 : 1, 947
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
511 : 1, 7, 73, 511
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,126,511,761, is 1.
Now, the common factors can be found like this.
947:947
126:2x 3x 3x 7
511:7x 73
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 46400865462/(1x7)
LCM = 46400865462/7
LCM = 6628695066
Thus, we can understand that the LCM of 947,126,511,761 is 6628695066.
