Factors of 9 = 1, 3, 9
Factors of 36 = 1, 3, 4, 6, 9, 12, 36
Common factors are 1, 3, 9.
Multiples of 18 = 18, 36, 54...
Multiples of 6 = 6, 12, 18,...
The first common multiple will be 18 And the next common multiples will be multiples of 18
Hence, first three common multiples of 18, 6 are 18, 36, 54.
The prime numbers between 50 and 100 are 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97, which are 10 in number.
20 expressed as a product of primes is 2 × 2 × 5.
The L.C.M. of coprimes is their product.
How many times the H.C.F. of 11, 33 and 88 is their L.C.M?
H.C.F. of 11, 33 and 88 is 11.
L.C.M. of 11,33 and 88 is 11 × 3 × 8 = 11 × 24 = H.C.F .× 24.
Coprime numbers are numbers that have no common factor other than 1.
The L.C.M. of two numbers is 10 times their H.C.F. Find the numbers.
Let the numbers be 24 and 240.
Then their H.C.F. = 24 and L.C.M. = 240.
Hence the required numbers are 24 and 240.
The sum of the first five multiples of 8 is 8 + 16 + 24 + 32 + 40 = 120.
Find the least 4−digit number that is divisible by 8.
The least 4digit number is1000, which is exactly divisible by 8 as 8 × 125 = 1000.
