To find the highest common factor (HCF) of 77 and 259, we need to factorize both numbers. The prime factorization of 77 is 7 x 11, and the prime factorization of 259 is 7 x 37. To find the HCF, we look for common prime factors in both numbers, which are 7. Therefore, the HCF of 77 and 259 is 7.

Well, isn't that a happy little question! To find the highest common factor of 77 and 259, we can start by listing the factors of both numbers. The factors of 77 are 1, 7, 11, and 77, while the factors of 259 are 1, 7, 37, and 259. The highest common factor is the largest number that appears in both lists, which in this case is 1. Remember, in the world of numbers, even the smallest factors can bring joy and harmony!

Well, honey, the highest common factor of 77 and 259 is 1. Those two numbers ain't got nothin' in common except for being odd. So, don't waste your time trying to find a bigger factor 'cause it just ain't gonna happen.

What are the factors and prime factors of 2695?

Since the number ends in '5' it will divide by '5' ( A prime Number) Hence 5)2695 = 539 7)539 = 77 77 = 11 11)11 = 1 Since 5,7,& 11 are prime numbers , they are the prime factos of 2695 Other compound factors are 35 , 49, 55 , 77 , 245, 385, 539


What are the factors and prime factors of 1155?

1155 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 1155 are 1, 3, 5, 7, 11, 15, 21, 33, 35, 55, 77, 105, 165, 231, 385, and 1155.The proper factors of 1155 are 1, 3, 5, 7, 11, 15, 21, 33, 35, 55, 77, 105, 165, 231, and 385 or,if the definition you are using excludes 1, they are 3, 5, 7, 11, 15, 21, 33, 35, 55, 77, 105, 165, 231, and 385.The prime factors of 1155 are 3, 5, 7, and 11.The 4 distinct prime factors (listing each prime factor only once) of 1155 are 3, 5, 7, and 11.The prime factorization of 1155 is 3 x 5 x 7 x 11.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.


What is the least common multiple of 21 77 and 63?

The LCM of a group of numbers is the smallest number that all of the given numbers will divide into.The LCM will always be the largest of the given numbers or its multiple. In our case, the largest number is 77. Since 21 and 63 will not divide into 77, the LCM will be a multiple of 77. That multiple will be the number 693 (77 x 9), because: 693/21 = 33 or 21 x 33 = 693; 693/63 = 11 or 63 x 11 = 693. Thus the LCM is 693.
