Given numbers are 777,407,172,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,407,172,164 is 60273444.
Find LCM of 777,407,172,164 with Prime Factorization
| 2 | 777, 407, 172, 164 |
| 2 | 777, 407, 86, 82 |
| 37 | 777, 407, 43, 41 |
| 21, 11, 43, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 37 x 21 x 11 x 43 x 41 = 60273444
Therefore, the lowest common multiple of 777,407,172,164 is 60273444.
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.
777 x 407 x 172 x 164 = 8920469712
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
407 : 1, 11, 37, 407
172 : 1, 2, 4, 43, 86, 172
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,407,172,164, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
407:11x 37
172:2x 2x 43
164:2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 37 = 148
Therefore, the value for common factors is 148.
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 = 8920469712/(1x148)
LCM = 8920469712/148
LCM = 60273444
Thus, we can understand that the LCM of 777,407,172,164 is 60273444.
