Question

The number 525 and 3000 are divisible by 3,5,15,25 and75 what is the HCF pls do it fast guy ' s

Answer 1

Hii friend,

Prime factorisation of 525 = 5× 5 × 3 × 7

Prime factorisation of 3000 = 2 × 2 × 2 × 3 × 5 × 5 × 5

Therefore,

HCF of 525 and 3000 = 5 × 5 × 3 = 75

HOPE IT WILL HELP YOU...... :-)

Answer 2

hye

==============================

there are 2 methods of solving it
 
1st method: the 2 numbers are  525 and 3000

they are divisible by 3,5,15,25 and 75 .

what is hcf?

hcf is the highest common factor.

so here the hcf in [3,5,15,25 and 75 ]

is 75 as it highest

so hcf of   525 and 3000 is 75

2nd method: lets recall a property

=>hcf *lcm = product of 2 numbers

=> lcm of 525 and 3000  = 21000[solve it by prime fctoisation]

=>hcf * 21000 = 525 *3000 

=> hcf * 21000 = 1575000

=>hcf = 1575000/21000

=> hcf =  75
