HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 916, 818 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 916, 818 is 2 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 812, 916, 818 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 812, 916, 818 is 2.
HCF(812, 916, 818) = 2
HCF of 812, 916, 818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 916, 818 is 2.
Highest Common Factor of 812,916,818 is 2
Step 1: Since 916 > 812, we apply the division lemma to 916 and 812, to get
916 = 812 x 1 + 104
Step 2: Since the reminder 812 ≠ 0, we apply division lemma to 104 and 812, to get
812 = 104 x 7 + 84
Step 3: We consider the new divisor 104 and the new remainder 84, and apply the division lemma to get
104 = 84 x 1 + 20
We consider the new divisor 84 and the new remainder 20,and apply the division lemma to get
84 = 20 x 4 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 812 and 916 is 4
Notice that 4 = HCF(20,4) = HCF(84,20) = HCF(104,84) = HCF(812,104) = HCF(916,812) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 4, we apply the division lemma to 818 and 4, to get
818 = 4 x 204 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 818 is 2
Notice that 2 = HCF(4,2) = HCF(818,4) .
