HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 204, 969 i.e. 51 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 204, 969 is 51 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, 204, 969 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, 204, 969 is 51.
HCF(816, 204, 969) = 51
HCF of 816, 204, 969 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, 204, 969 is 51.
Highest Common Factor of 816,204,969 is 51
Step 1: Since 816 > 204, we apply the division lemma to 816 and 204, to get
816 = 204 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 204, the HCF of 816 and 204 is 204
Notice that 204 = HCF(816,204) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 969 > 204, we apply the division lemma to 969 and 204, to get
969 = 204 x 4 + 153
Step 2: Since the reminder 204 ≠ 0, we apply division lemma to 153 and 204, to get
204 = 153 x 1 + 51
Step 3: We consider the new divisor 153 and the new remainder 51, and apply the division lemma to get
153 = 51 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 51, the HCF of 204 and 969 is 51
Notice that 51 = HCF(153,51) = HCF(204,153) = HCF(969,204) .
