Find HCF of 135 and 225 by other methods |
|
Answer» Divison method , eculid\'s algorithm lemma , prime factorization method Here 225 > 135 we always divide greater number with smaller one.Divide 225 by 135 we get 1 quotient and 90 as remainder so that225= 135*1 + 90Divide 135 by 90 we get 1 quotient and 45 as remainder so that135= 90*1 + 45Divide 90 by 45 we get 2 quotient and no remainder so we can write it as90 = 2*45+ 0As there are no remainder so deviser 45 is our HCF |

What is co prime numbers |
|
Answer» For example, 2 and 3 are two prime numbers. Factors of 2 are 1, 2 and factors of 3 are 1, 3. The only common factor is 1 and hence is co-prime. Any two successive numbers/ integers are always co-prime: Take any consecutive number such as 2, 3 or 3, 4 or 5, 6 and so on; they have 1 hcf. How No its wrong Numbers that are only divisible by themselves like 2 , 1 etc Two numbers with only 1 as a comon factor are called co prime no. |

Can two numbers have 18 as their HCF and 380 as their LCM ? Give reasons. |
| Answer» We know that HCF of two numbers is a divisor of their LCM. Here, 18 is not a divisor of 380.But 380 = 18×21+2Here 2 is remainder so 380 is not divisible by 18.So, 18 and 380 cannot be respectively HCF and LCM of two numbers. | |
