The hcf of two numbers is 11 and there l.c.m is 693. if one of the numbers is 77, then the other number is ​​

Answer 1

Answer:

Product of two numbers is equls to product of LCM & HCF.

One of the number is 77,let the second number is b

LCM is 693and HCF is 11

77 X b = 693 X 11

b=99

Answer 2

GIVEN

• H.C.F of the numbers = 11
• L.C.M of the numbers = 693
• One number = 77

TO FIND

• Second number

SOLUTION

We know that

HCF × LCM = Product of two numbers

⟹ 693 × 11 = 77 × y

⟹ 7623 = 77y

⟹ y = 7623/77

⟹ y = 99

∴ The second number is 99.
