HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 495 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 495 is 3 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, 495 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, 495 is 3.
HCF(816, 495) = 3
HCF of 816, 495 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, 495 is 3.
Highest Common Factor of 816,495 is 3
Step 1: Since 816 > 495, we apply the division lemma to 816 and 495, to get
816 = 495 x 1 + 321
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 321 and 495, to get
495 = 321 x 1 + 174
Step 3: We consider the new divisor 321 and the new remainder 174, and apply the division lemma to get
321 = 174 x 1 + 147
We consider the new divisor 174 and the new remainder 147,and apply the division lemma to get
174 = 147 x 1 + 27
We consider the new divisor 147 and the new remainder 27,and apply the division lemma to get
147 = 27 x 5 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 816 and 495 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(147,27) = HCF(174,147) = HCF(321,174) = HCF(495,321) = HCF(816,495) .
