Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
Check it.
30 x 42 = 1260
210 x 6 = 1260
It checks.
HCF is 48 and LCM is 576
hcf = 42, lcm = 84.
The HCF is: 2The LCM is: 2,520
hcf: 1 lcm: 112,038
No. The LCM MUST be a multiple of the HCF.
it means lowest common multiple. the opposite to it is hcf or highest common factor ^_^
LCM is 20 and the hcf is 10
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
HCF = 3... LCM = 18 !
HCF is 60 and the LCM is 360
HCF is 48 and LCM is 576
hcf = 42, lcm = 84.
The HCF is: 2The LCM is: 2,520
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
i really need help on maths home work can you help me thank you the maths is hcf of prime factors of 196 60 and 28 primes factors 735 and 639 prim factors
hcf: 1 lcm: 112,038
No. The LCM MUST be a multiple of the HCF.
