Question

and 580.100
It the LCM of 56 and 70 is 280, find their HCF.4
The product of two numbers is 7623. If thejr LCM is 693, find their HCF.
The HCF of two numbers is 23​

Answer 1

Answer:

1) HCF =14

2) HCF= 11

Step-by-step explanation:

1) 1st no. = 56

2nd no. = 70

LCM= 280

HCF=?

So, product of two numbers= HCF×LCM

56×70=HCF×280

3920=HCF×280

3920÷280=HCF

HCF=14

2) Product of two numbers= 7623

LCM=693

HCF=?

So, Product of two numbers= HCF×LCM

7623= HCF×693

7623÷693=HCF

HCF=11
