Question

Find out the HCF and LCM of 135, 126, 60 and 255

Answer 1

Answer:

64,260 and 3

Step-by-step explanation:

2  | 135, 126, 60, 255

 3 | 135, 63,  30, 255

   5 |  45, 21, 10, 85

    3  |  9, 21, 2, 17

          3, 7,  2,  17

LCM = 2*3*5*3*3*7*2*17 = 64,260

135 = 3*5*3*3

126 = 2*3*3*7

60 = 2*3*5*2

255 = 3*5*17

HCF = 3
