Answer :
Lcm of 60 and n = 420
Stated: n <90 and a multiple of 6
420/60 = 7 thus n must be a multiple of 7
Therefore n =42 or 84
Stated: n <90 and a multiple of 6
420/60 = 7 thus n must be a multiple of 7
Therefore n =42 or 84
The value of n will be either 42 or 84.
What is the lowest common multiple?
The smallest positive integer that is divisible by both a and b is known as the least common multiple, lowest common multiple, or smallest common multiple of two integers, or lcm(a, b), in mathematics and number theory.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
It is given that Lcm of 60 and n is 420 and n is a multiple of 6 less than 90. Then the value n will be calculated as given below:-
Divide the number 420 by 60 then the 7 is the constant term the other number must be the multiple of 7.
420/60 = 7
The other number multiple of 7 will be:-
n =42 or 84
Therefore, the value of n will be either 42 or 84.
