Question

Both h.c.f and l.c.m of 3,9,18,25 in process ​

Answer 1

Answer:

LCM = 450

HCF = 1

Step-by-step explanation:

FOR LCM—

The multiples of the given numbers are as follows,

3 = 3,6,9,12,15,18,.................,444,447,450

9 = 9,18,27,36,............,432,441,450

18 = 18,36,54,72,90,108,..............,432,450

25 = 25,50,75,100,125,150,175,.............,400,425,450

We notice that they have one multiple( i.e. 450 )in common so, their LCM = 450

FOR HCF—

The factors of the given numbers are as follows,

3 = 3 * 1

9 = 3 * 3 * 1

18 = 3 * 3 * 2 * 1

25 = 5 * 5 * 1

We notice that the only highest common factor among the above lists is 1, so the HCF = 1
