The greatest common factor or the highest common factor is the highest number that divides exactly into two or more numbers. 24: 1, 2, 3, 4, 6, 8, 12, 24 30: 1, 2, 3, 5, 6, 10, 15, 30 The GCF of 24 and 30 is 6.
An HCF of 1 means that the two numbers share no prime factors. An LCM of 30, means the numbers have between them prime factors of 2, 3 and 5. Thus any product combination of these factors will give a possible answer. You could have: 2 and 3x5 (15) 3 and 2x5 (10) or 5 and 2x3 (6)
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260

Prime factorization is one of the ways you find the HCF.
The GCF is 6.

Use GCF instead of HCF. 6 and 30 would be those numbers...
