HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 772, 677 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 772, 677 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 772, 677 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 772, 677 is 1.
HCF(772, 677) = 1
HCF of 772, 677 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 772, 677 is 1.
Highest Common Factor of 772,677 is 1
Step 1: Since 772 > 677, we apply the division lemma to 772 and 677, to get
772 = 677 x 1 + 95
Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 95 and 677, to get
677 = 95 x 7 + 12
Step 3: We consider the new divisor 95 and the new remainder 12, and apply the division lemma to get
95 = 12 x 7 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 772 and 677 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(95,12) = HCF(677,95) = HCF(772,677) .
