1.	Calculate the HCF of 90 and 126 by prime factorization and EDL and verify by both the methods
Answer» 90 = 2 × 32 × 5; 126 = 2 × 32 × 7; Multiply all the COMMON prime factors, by the lowest exponents. Greatest (highest) common factor (DIVISOR): gcf, hcf, GCD (90; 126) = 2 × 32 gcf, hcf, gcd (90; 126) = 2 × 32 = 18; the NUMBERS have common prime factors

Calculate the HCF of 90 and 126 by prime factorization and EDL and verify by both the methods

Answer»

90 = 2 × 32 × 5;

126 = 2 × 32 × 7;

Multiply all the COMMON prime factors, by the lowest exponents.

Greatest (highest) common factor (DIVISOR):

gcf, hcf, GCD (90; 126) = 2 × 32

gcf, hcf, gcd (90; 126) = 2 × 32 = 18;

the NUMBERS have common prime factors
