HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 677 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 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 787, 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 787, 677 is 1.
HCF(787, 677) = 1
HCF of 787, 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 787, 677 is 1.
Highest Common Factor of 787,677 is 1
Step 1: Since 787 > 677, we apply the division lemma to 787 and 677, to get
787 = 677 x 1 + 110
Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 110 and 677, to get
677 = 110 x 6 + 17
Step 3: We consider the new divisor 110 and the new remainder 17, and apply the division lemma to get
110 = 17 x 6 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 677 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(110,17) = HCF(677,110) = HCF(787,677) .
