Step-by-step explanation:

I will do a) and b) part of each question please do the rest of all by yourself

1) a = 238756+548760+23456

= 810972

b) 45+934+65712+435671

= 503262

2) Hcf of 25,35

first find the lcm of that and see what is common in this for this hcf will be 5

b) Lcm of 12,18,20

will be 2× 2×3×5×3 = 180

Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

2. Solve the following:-

(a) 2387456 + 548760 + 23456 = 2959672

(b) 45 + 934 + 65712 + 435671 = 502362

(c) 5761245 – 2135432 = 3625813

(d) 7020072 – 4301513 = 2718559

(e) 536 x 305 = 163480

(f) 3425 x 263 = 900775

(g) 2027456 / 79 = 25664

(i)1532456 / 37 = 41417.7297297

3. Find the LCM or HCF as required:-

(a) HCF of 25, 35 =  

Find the prime factors of all integers

25 = 5 x 5

35 = 5 x 7

The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (25 & 35).

HCF(25, 35) = 5

(b) LCM of 12, 18, 20  (refer to image)

2 x 2 x 3 x 5 x 3 = 180

LCM(12, 18, 20) = 180

(c) HCF of 36, 44 and 60

Find the prime factors of all integers

36 = 2 x 2 x 3 x 3

44 = 2 x 2 x 11

60 = 2 x 2 x 3 x 5

The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (36, 44 & 60).

HCF(36, 44, 60) = 4

(d) LCM of 48, 60 and 84 (refer to image)

12 x 4 x 5 x 7 = 1680

LCM(48, 60, 84) = 1680
