The HCF of the given four numbers is 1
These numbers go evenly into both 800 and 160 evenly: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160.
There can be only one greatest common factor for any set of numbers. GCF(40, 20) = 20.
The LCM of 8, 10, and 20 is 40. Multiples of 8: 8, 16, 24, 32, 40, 48...... Multiples of 10: 10, 20, 30, 40, 50, 60...... Multiples of 20: 20, 40, 60, 80 The smallest number that all three numbers go into evenly is 40. Therefore the LCM of 8, 10, and 20 is 40.
The GCF of these numbers is 40.
The GCF of 20 and 40 is 20.
There are 40 odd numbers between 20 and 100. Remember that an odd number is every second number. There are 80 numbers between 20 and 100, so there are 40 odd numbers and 40 even numbers.
Even numbers are numbers which are multiples of 2 (they can be divided by 2). 40\2 = 20 This means that 40 is an even number.
The prime numbers between 20 and 40 are 23, 29, 31 and 37 that is 4 out of 20 or 1 to 5
No number between 20 and 40 is divisible by all 4 numbers. The smallest number divisible by all 4 of those numbers is: 56
tere are an infinite number of numbers that divide into 40 i.e. 0.00000000etc 1 to 39.00000000etc to 40
1, 2, 4, 5, 8, 10, 20, 40.
The prime numbers between 20 and 40 are 23, 29, 31 and 37 that is 4 out of 20 or 1 to 5
The prime numbers between 20 and 40 are 23, 29, 31 and 37 that is 4 out of 20 or 1 to 5
The numbers are: -2 and -20
2, 4, 5, 8, 10, 20
10, 20, 30, 40, .....100, 110, ... the list goes on forever!
It is 27.5, the number halfway between the two middle numbers.
