Answer:
HCF: 1
LCM: 84
Step-by-step explanation:
7 is a prime number. Nothing but 1 and 7 divide into which means that twelve and 7 have no highest common factor but 1.
The lowest common multiply (because 12 and 7 are prime to each other ) is 12 * 7 = 84
Answer:
LCM = 84 GCF = 1
Step-by-step explanation:
LCM of 7 and 12 is 84.
GCF(7,12) = 1
LCM(7,12) = ( 7 × 12) / 1
LCM(7,12) = 84 / 1
LCM(7,12) = 84
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
GCF of 7 and 12 is 1. Now calculate the prime factors of 7 and 12, then find the greatest common factor (greatest common divisor) of the numbers.
To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
