HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 887, 767 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 887, 767 is 1 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 820, 887, 767 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 820, 887, 767 is 1.
HCF(820, 887, 767) = 1
HCF of 820, 887, 767 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 887, 767 is 1.
Highest Common Factor of 820,887,767 is 1
Step 1: Since 887 > 820, we apply the division lemma to 887 and 820, to get
887 = 820 x 1 + 67
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 67 and 820, to get
820 = 67 x 12 + 16
Step 3: We consider the new divisor 67 and the new remainder 16, and apply the division lemma to get
67 = 16 x 4 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 887 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(67,16) = HCF(820,67) = HCF(887,820) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 767 > 1, we apply the division lemma to 767 and 1, to get
767 = 1 x 767 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 767 is 1
Notice that 1 = HCF(767,1) .
