Question

Hcf and lcm of 28,36,45

Answer 1

Step-by-step explanation:

LCM of 28, 36, and 45 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 22 × 32 × 51 × 71 = 1260. Hence, the LCM of 28, 36, and 45 by prime factorization is 1260.

Answer 2

Answer:

Step-by-step explanation:

first, you have to find the PRIME FACTOR of each and for HCF you have to take the highest common factor from each and from LCM you have to find lease common multiple from each

FOR HCF

PRIME Factor of 28

28 = 2*2*7

36=2*2*3*3

45 = 3*3*5

HCF = 1  Because the highest common factor from each is only 1

FOR LCM

PRIME FACTOR

28 = 2*2*7

36=2*2*3*3

45 = 3*3*5

LCM = 2*2*3*3*5*7 = 1260
