Question

Find the hcf and lcm of 6 72 and 120 using the prime factorization methods.show that product of three

Answer 1

Here we have :-

6 = 2 × 3

72 => 2 × 2 × 2 × 3 × 3 = 2³ × 3²

120 => 2 × 2 × 2 × 3 × 5 = 2³ × 3¹ × 5¹

HCF(6,72,120) => 2¹ × 3¹ = 6

LCM(6,72,120) => 2³ × 3² × 5¹ = 360

Answer 2

Answer:

144

Step-by-step explanation:

LCM= 3x2x4x3x5=360

as a product of numbers =LCM x HCF

          6 x 72 x 120 =  HCF x 360

             HCF = 144
