Given numbers are 770,55,622,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,55,622,697 is 166910590.
Find LCM of 770,55,622,697 with Prime Factorization
| 2 | 770, 55, 622, 697 |
| 5 | 385, 55, 311, 697 |
| 11 | 77, 11, 311, 697 |
| 7, 1, 311, 697 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 1 x 311 x 697 = 166910590
Therefore, the lowest common multiple of 770,55,622,697 is 166910590.
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.
770 x 55 x 622 x 697 = 18360164900
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
55 : 1, 5, 11, 55
622 : 1, 2, 311, 622
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,55,622,697, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
55:5x 11
622:2x 311
697:17x 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 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 18360164900/(1x110)
LCM = 18360164900/110
LCM = 166910590
Thus, we can understand that the LCM of 770,55,622,697 is 166910590.
