which pair of numbers from 1 to 30 has the LCM OF 120
The lowest common multiple of these three numbers is 20.
The LCM of 4 and 5 is 20.
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 10: 10, 20, 30 15: 15, 30 The LCM of 10 and 15 is 30.
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
20 and 100.GCF is 20, and LCM is 100.
How about: 4 and 5
4 and 40 8 and 20
This cannot be answered because an LCM (least common multiple) is the smallest positive number that is a multiple of two or more numbers.
LCM is least common multiple of two or more numbers. LCM of 5 and 20 is 20.
The least common multiple is the smallest number that is multiple of two or more numbers. The LCM of 2, 4, and 5 is 20.
LCM(Least Common Multiple) as the name suggests is the common multiple of two numbers. Thus, LCM of a single number cannot be found out.
The LCM of 10 and 20 is 20.
The Least Common Multiple (LCM) of 10 and 20 is 20. Since 20 is a multiple of 10, it is automatically the LCM of the set.20 is.
LCM is least common multiple of two or more numbers. LCM of 4 and 5 is 20.
There must be at least 2 numbers before a LCM can be determined. However, in your question, you only mentioned one number. Thus, it is impossible to find a LCM.
A single number, 20, does not have a lowest common multiple! So there are no two numbers to go in.
