The GCF is 15.
15
225 and 15, respectively.
HCF = 15
It is: 15
-75
6
The LCM of 30, 45 and 75 is 450.
dBw=dBm-30 then 75-30=45 dBw dBw=dBm-30 then 75-30=45 dBw dBw=dBm-30 then 75-30=45 dBw
-45 - 30 = -75
The sum of 30 and 45 is 75.
To find the LCM of two numbers, you first split them into their prime factors: 30 = 2x3x5 75 = 3x5x5 Next you need to work out the HCF. Here, the HCF will be 3x5 = 15. Finally, you multiply the numbers together and divide by the HCF. 30x75/15 = 150. Therefore the LCM of 30 and 75 is 150.
