Question

find the H. C. F and L. C. M of 576 and 1440

Answer 1

Hcf of 576and 1440 =288
Lcm of 576 and1440=2880
hope it helps you

Answer 2

HCF of 576 and 1440

Factorization of 576 = 2 * 2 * 2 * 2 * 2 * 2 * 3 * 3

Factorization of 1440 = 2 * 2 * 2 * 2 * 2 * 3 * 3 * 5

The underlined numbers are common factors

HCF = 2 * 2 * 2 * 2 * 2 * 3 * 3 = 288

LCM = The product of numbers / HCF

576 * 1440 / 288

= 2880

The HCF and LCM are 288 and 2880 respectively
