What is the Least Common Multiple of 1 and 36?
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
Least common multiple (LCM) of 1 and 36 is 36.
LCM(1,36) = 36
Least Common Multiple of 1 and 36 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1 and 36, than apply into the LCM equation.
GCF(1,36) = 1
LCM(1,36) = ( 1 × 36) / 1
LCM(1,36) = 36 / 1
LCM(1,36) = 36
Least Common Multiple (LCM) of 1 and 36 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 1 and 36. First we will calculate the prime factors of 1 and 36.
Prime Factorization of 36
Prime factors of 36 are 2, 3. Prime factorization of 36 in exponential form is:
36 = 22 × 32
Now multiplying the highest exponent prime factors to calculate the LCM of 1 and 36.
LCM(1,36) = 22 × 32
LCM(1,36) = 36
