The Highest Common Factor (HCF) of 20, 25, 35, and 45 is 5. To find the HCF, you need to determine the common factors of all the numbers and then identify the highest one they all share. In this case, the factors of the numbers are as follows: 20 (1, 2, 4, 5, 10, 20), 25 (1, 5, 25), 35 (1, 5, 7, 35), and 45 (1, 3, 5, 9, 15, 45). The highest common factor among all these numbers is 5.
The Least Common Multiple (LCM) for 20 25 35 and 45 is 6,300.
1575 1575/25=63 1575/35=45 and 1575/45=35
Average = Sum of numbers/ No. of numbers 45 + 25 + 35 = 105 105/3 = 35
15, 20, 25, 30, 35, 40, 45
20, 25, 30, 35, 40, 45, 50, 55.
