HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 8657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 8657 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 778, 8657 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 778, 8657 is 1.
HCF(778, 8657) = 1
HCF of 778, 8657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 778, 8657 is 1.
Highest Common Factor of 778,8657 is 1
Step 1: Since 8657 > 778, we apply the division lemma to 8657 and 778, to get
8657 = 778 x 11 + 99
Step 2: Since the reminder 778 ≠ 0, we apply division lemma to 99 and 778, to get
778 = 99 x 7 + 85
Step 3: We consider the new divisor 99 and the new remainder 85, and apply the division lemma to get
99 = 85 x 1 + 14
We consider the new divisor 85 and the new remainder 14,and apply the division lemma to get
85 = 14 x 6 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 778 and 8657 is 1
Notice that 1 = HCF(14,1) = HCF(85,14) = HCF(99,85) = HCF(778,99) = HCF(8657,778) .
