The GCF is 5.
The factors of 65 are 1, 5, 13, 65 The factors of 155 are 1, 5, 31, 155 The largest matching number is 5. Therefore the GCF of 65 and 155 is 5.
The GCF is 5.
The highest common multiple is an infinite number and probably not of much use to you. The GCF is 5. The LCM is 2015.
Their highest common factor is 1
65 factors to [5 13] 145 factors to [5 29] common factors: [5] Answer is 5. ■
Same as the highest common factor between 26 and 13. 13 is the remainder of the division of 65 by 26.
To find the highest common factor of two numbers, you need to determine the largest number that divides evenly into both numbers. For 65 and 185, you can start by finding the factors of each number: 65 (1, 5, 13, 65) and 185 (1, 5, 37, 185). The common factors between the two numbers are 1 and 5. Therefore, the highest common factor of 65 and 185 is 5.
The greatest common factor of 26 and 65 is 13.13x2=2613x5=65
The first step to find the gcf of 85 and 145 is to list the factors of each number. The factors of 85 are 1, 5, 17 and 85. The factors of 145 are 1, 5, 29 and 145. So, the Greatest Common Factor for these numbers is 5 because it divides all them without a remainder.
The common factors of 65 are 1,5,13,and65
1 and 5 are the common factors of 65 and 25.
LCM of two numbers = product/HCF; 65 = 5 x 13, 155 = 5 x 31 so HCF is 5 and LCM is 65 x 155/5 = 2015
