To calculate the LCM, you first have to split the numbers up into their prime factors: 64 = 2x2x2x2x2x2 72 = 2x2x2x3x3 The next step is to calculate the HCF. In this case it will be 2x2x2 = 8. Finally, you multiply the two numbers and divide by the HCF: 64x72/8 = 576 And therefore the LCM of 64 and 72 is 576.
List the prime factors of each. 18 = 2 x 3 x 3, 42 = 2 x 3 x 7 Common factors are 2 and 3 so HCF = 6.
The HCF is 7.
The HCF is: 2
The HCF is 1.

To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
In this context, HCF should mean hundred cubic feet, which is approximately 748 US gallons (see related link). To calculate it, use 231 cubic inches to a US gallon, and a cubic foot is (12 in)³ = 1728 cubic inches.
The HCF is 5.
the HCF is 6
The HCF is 1
HCF = 14
Oh honey, the Highest Common Factor (HCF) of 240 and 228 is 12. You can thank good old 12 for being the largest number that can divide both 240 and 228 without leaving a remainder. So, there you have it, 12 is the winner in this math showdown.
The HCF of 16 & 33 is... 1
Oh, I see you're curious about what numbers can go into both 10 and 84. Let's take a moment to appreciate the beauty of numbers working together. The numbers that can go into both 10 and 84 are 1, 2, and 5. It's like a happy little math family coming together to create harmony.
