MaxineThe Greatest Common Factor (GCF) of x-1 is one. The reason for this is because you don't know what the value of x is and there is only one x in the equation (plus there is only one 1). No other number can be multiplied to equal x-1 without the knowledge of the value of x. So, with that in mind, the equation can be written as 1(x-1) to show that the GCF is 1. The answer to the equation 1(x-1) is x-1 because 1 multiplied by x is 1x (written as just x) and 1 multiplied by -1 is -1 (a negative multiplied by a positive equals a negative).

What is the least common multiple of 35 and 77?
The LCM is: 19257 = 7 x 1275 = 5 x 5 x 1177 = 7 x 11Since 77 is a multiple of 7, find the least common multiple of 275 and 77.5 x 5 x 7 x 11 = 1925
What is the least common multiple of 40 and 60?
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 40 and 60 is 120.120Factor them.2 x 2 x 2 x 5 = 402 x 2 x 3 x 5 = 60Select the highest amount of each factor.2 x 2 x 2 x 3 x 5 = 120, the LCMThe Least Common Multiple of 40, 60: 120
What is the least common multiple for 30?
Factorise into prime numbers and collect the least set of prime numbers: 8 = 2 x 2 x 2 30 = 5 x 3 x 2 Least set is 2 x 2 x 2 x 5 x 3 (miss out the 2 - it appears in both 30 primes and 8 primes) Least common multiple is 2 x 2 x 2 x 5 x 3 = 120
What is the least common multiple of 50 and 80?
If x is the multiple of y then LCM of x and y is x. Here, 80 is the multiple of 10 therefore LCM of 10 & 80 is 80.
What is the least common multiple of 22 and 30?
The least common factor of any set of positive integers is 1.
