The Highest Common Factor (HCF) of 35, 84, and 91 is 7. To find the HCF, you can first find the prime factors of each number: 35 = 5 x 7, 84 = 2^2 x 3 x 7, and 91 = 7 x 13. Then, identify the common prime factors among the numbers, which in this case is 7. Finally, multiply the common prime factors to get the HCF, which is 7.
The HCF of 21, 84 and 91 is.... 1 ! The number 91 is a prime number.
It is: 7
It is: 1
The GCF is 7.
Well, isn't that a happy little math question! To find the highest common factor (HCF) of 28, 84, and 91, we can start by listing the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 91 are 1, 7, 13, and 91. The largest number that appears in all three lists is 7, so the HCF of 28, 84, and 91 is 7.
