Question

Three measuring rods 64 cm, 80 cm and 96 cm in length. Find the least length of cloth that can be measured exact number of times using anyone of the above rods.

Answer 1

Answer:

960 cm

Step-by-step explanation:

lcm of 64,80,96 =960

Answer 2

Answer:

the length of cloth that can be measured exact no of time = 1920 cm

Step-by-step explanation:

Given : three measuring rods is 64 cm , 80 cm, 96 cm

find the least length of cloth

first find the L.C.M of  64,80,96

using prime factorization method :

64 =  2 x 8 x 4

80 = 2 x 8 x 5

96 = 2 x 8 x 6

L.C.M of 64,80,96 = 2 x 8 x 4 x 5 x 6 =1920

hence ,the length of cloth that can be measured exact no of time using  any of the above rods = 1920 cm
