LCM (Least Common Multiple) and HCF (Highest Common Factor), also known as GCD (Greatest Common Divisor), are mathematical concepts that have been used since ancient times in various cultures. They were initially used in solving problems related to fractions and division, and over time, their properties and applications have been further developed in number theory and algebra. Their concepts have evolved and been refined through the works of mathematicians like Euclid, Fermat, and Euler.

Reviewing GCF, LCM, and prime factorization in 6th grade math is important because it helps students develop essential foundational skills in number theory and problem-solving. These concepts are fundamental to understanding fractions, simplifying expressions, and solving word problems. Mastery of these topics also provides a solid basis for more advanced mathematical concepts in higher grades.
Pedro Cabral attended school in the early 1500s in Portugal. He came from a noble family and received a good education, which likely influenced his decision to become an explorer and navigator.
Albert Einstein taught at the Institute for Advanced Study in Princeton, New Jersey.
The concept of Response to Intervention (RTI) was developed and pioneered by educational researchers and practitioners in the field of special education. It was influenced by the work of educational psychologists and scholars such as Douglas Fuchs and Lynn S. Fuchs.
LCM is 20 and the hcf is 10
HCF = 3... LCM = 18 !
HCF is 60 and the LCM is 360
hcf is 1 and LCM is 35
HCF is 48 and LCM is 576
hcf = 42, lcm = 84.
The HCF is: 2The LCM is: 2,520
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
hcf: 1 lcm: 112,038
No. The LCM MUST be a multiple of the HCF.
LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
5 and 10 lcm- 10 and hcf= 5
