HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 710, 820, 808 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 710, 820, 808 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 710, 820, 808 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 710, 820, 808 is 2.
HCF(710, 820, 808) = 2
HCF of 710, 820, 808 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 710, 820, 808 is 2.
Highest Common Factor of 710,820,808 is 2
Step 1: Since 820 > 710, we apply the division lemma to 820 and 710, to get
820 = 710 x 1 + 110
Step 2: Since the reminder 710 ≠ 0, we apply division lemma to 110 and 710, to get
710 = 110 x 6 + 50
Step 3: We consider the new divisor 110 and the new remainder 50, and apply the division lemma to get
110 = 50 x 2 + 10
We consider the new divisor 50 and the new remainder 10, and apply the division lemma to get
50 = 10 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 710 and 820 is 10
Notice that 10 = HCF(50,10) = HCF(110,50) = HCF(710,110) = HCF(820,710) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 808 > 10, we apply the division lemma to 808 and 10, to get
808 = 10 x 80 + 8
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 8 and 10, to get
10 = 8 x 1 + 2
Step 3: We consider the new divisor 8 and the new remainder 2, and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 808 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(808,10) .
