please tell me the answer fast of all
Answers
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

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
