The GCF is: 1
The greatest common factor of the numbers 15 and 44 is 1.
Since 15 is a factor of 30, it is automatically the GCF.
The HCF is: 5
The common factors are: 1, 5
It is 30
60
The least common multiple of 15 , 35 = 105
The Least Common Multiple (LCM) of 15 and 45 is 45.
The Least Common Multiple (LCM) of 15 and 18 is 90.
The Least Common Multiple (LCM) for 15 75 is 75.
It is 3
To find the least common multiples of two numbers, you have to first split them into their prime factors: 15 = 3x5 10 = 2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor, so one of these can be discarded. Take every other prime factor (2, 3 and 5) and multiply them together: 2x3x5 = 30 Thus the least common multiple of 15 and 10 is 30.
