HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 876, 820, 98 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 876, 820, 98 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 876, 820, 98 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 876, 820, 98 is 2.
HCF(876, 820, 98) = 2
HCF of 876, 820, 98 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 876, 820, 98 is 2.
Highest Common Factor of 876,820,98 is 2
Step 1: Since 876 > 820, we apply the division lemma to 876 and 820, to get
876 = 820 x 1 + 56
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 56 and 820, to get
820 = 56 x 14 + 36
Step 3: We consider the new divisor 56 and the new remainder 36, and apply the division lemma to get
56 = 36 x 1 + 20
We consider the new divisor 36 and the new remainder 20,and apply the division lemma to get
36 = 20 x 1 + 16
We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get
20 = 16 x 1 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 876 and 820 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(36,20) = HCF(56,36) = HCF(820,56) = HCF(876,820) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 98 > 4, we apply the division lemma to 98 and 4, to get
98 = 4 x 24 + 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 98 is 2
Notice that 2 = HCF(4,2) = HCF(98,4) .
