Question

find the lcm of 25/7, 15/28, 20/21​

Answer 1

Answer:

300/7

Step-by-step explanation:

find the lcm of 25/7, 15/28, 20/21​

to find LCM of  25/7  , 15/28  & 20/21

we will find LCM of Numerators  & HCF of Denominator

25 = 5 * 5

15 = 3 * 5

20 = 2 * 2 * 5

LCM = 2 * 2 * 3 * 5 * 5  = 300

7  = 1 * 7

28 = 2 * 2 * 7

21 = 3 * 7

HCF = 7

So LCM =  LCM of Numerator / HCF of Denominator   = 300/7
