Given numbers are 771,755,655,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,755,655,671 is 51167611605.
Find LCM of 771,755,655,671 with Prime Factorization
| 5 | 771, 755, 655, 671 |
| 771, 151, 131, 671 |
Multiply the prime numbers at the bottom and the left side.
5 x 771 x 151 x 131 x 671 = 51167611605
Therefore, the lowest common multiple of 771,755,655,671 is 51167611605.
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.
771 x 755 x 655 x 671 = 255838058025
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.
771 : 1, 3, 257, 771
755 : 1, 5, 151, 755
655 : 1, 5, 131, 655
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,755,655,671, is 1.
Now, the common factors can be found like this.
771:3x 257
755:5x 151
655:5x 131
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 255838058025/(1x5)
LCM = 255838058025/5
LCM = 51167611605
Thus, we can understand that the LCM of 771,755,655,671 is 51167611605.
