Both 25 and 4 are factors of 100 and are square numbers, 25 is 52 and 4 is 22. 100 and 1 are also factors of 100, and are also square numbers: 1 is 12 and 100 is 102.
100
25 + 25 + 25 + 25 = 100
The hcf of both numbers is just 1
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 25: 50, 75, 100 50: 50, 100 100: 100 The least common multiple for 25, 50 and 100 and is 100.
25. its the greatest number that goes into both numbers evenly
Both 25 and 4 are factors of 100 and are square numbers, 25 is 52 and 4 is 22. 100 and 1 are also factors of 100, and are also square numbers: 1 is 12 and 100 is 102.
Number of Prime Numbers from 1 to 100 is 25. From 1 to 50 it was 15 From 50 to 100 it was 10
The total number of prime numbers less than 100 is 25.
4 and 25 are not prime numbers.
The GCF is the greatest common factor. The GCF of 75 and 100 is 25. This means that this is the largest number that will fit into both numbers, equally.
That means that you are supposed to multiply both numbers.
25 and 29 are both numbers between 20 and 30, 10 and 50, 1 and 100, etc. They are both 2-digit numbers. They both have a 2 in the hundred's place. They are both whole numbers.
20 and 50 10 and 25
They are both divisible by 1, 5, 25
75 composite numbers are there till 100. 100-25=75. Composite numbers are numbers greater than 1 but not prime numbers.
The [mean] average of 5 numbers is 25, so their total is 5 x 25 = 125 The [mean] average of 4 numbers is 25, so their total is 4 x 25 = 100 → the excluded number is 125 - 100 = 25. Alternatively, as the average doesn't change, the excluded number must be the average, ie 25.
