Question

the lcm and gcd of two numbers are 20 and 35 respectively. can you find the numbers​

Answer 1

Step-by-step explanation:

We know that LCM×HCF=Product of two numbers, therefore, we have

7a×7b=(7×140)

⇒49ab=7×140

⇒ab=20

Two co-primes with product 20 are 4 and 5.

Therefore, the required number is (7×4,7×5)=(28,35)

The sum of these numbers is 28+35=63

Hence, the sum of the numbers is 63

Answer 2

Answer: LCM of 20 and 35 is 140.

Explanation:

The LCM of two non-zero integers, x(20) and y(35), is the smallest positive integer m(140) that is divisible by both x(20) and y(35) without any remainder.
