HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 888, 85 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 888, 85 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 816, 888, 85 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 816, 888, 85 is 1.
HCF(816, 888, 85) = 1
HCF of 816, 888, 85 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 888, 85 is 1.
Highest Common Factor of 816,888,85 is 1
Step 1: Since 888 > 816, we apply the division lemma to 888 and 816, to get
888 = 816 x 1 + 72
Step 2: Since the reminder 816 ≠ 0, we apply division lemma to 72 and 816, to get
816 = 72 x 11 + 24
Step 3: We consider the new divisor 72 and the new remainder 24, and apply the division lemma to get
72 = 24 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 816 and 888 is 24
Notice that 24 = HCF(72,24) = HCF(816,72) = HCF(888,816) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 85 > 24, we apply the division lemma to 85 and 24, to get
85 = 24 x 3 + 13
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 13 and 24, to get
24 = 13 x 1 + 11
Step 3: We consider the new divisor 13 and the new remainder 11, and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 24 and 85 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(85,24) .
