Answer 1

Answer:

Heya ✋

Let see your answer !!!!!

Given that

Product of two numbers = 20,280

HCF = 13

LCM = ?

Solution

HCF × LCM = Product of two numbers

=> 13 × LCM = 20,280

=> LCM = 20,280/13

=> LCM = 1,560

Answer 2

Step-by-step explanation:

let , 1st no = A = 20

2nd no = B = 280

then , A×B = 20 × 280 = 5600

HCF = 13

LCM = ?

As, A×B = HCF × LCM

LCM = A×B / HCF

putting values

LCM = 5600 / 13

LCM = 430.7
