HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8156, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8156, 657 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 8156, 657 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 8156, 657 is 1.
HCF(8156, 657) = 1
HCF of 8156, 657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8156, 657 is 1.
Highest Common Factor of 8156,657 is 1
Step 1: Since 8156 > 657, we apply the division lemma to 8156 and 657, to get
8156 = 657 x 12 + 272
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 272 and 657, to get
657 = 272 x 2 + 113
Step 3: We consider the new divisor 272 and the new remainder 113, and apply the division lemma to get
272 = 113 x 2 + 46
We consider the new divisor 113 and the new remainder 46,and apply the division lemma to get
113 = 46 x 2 + 21
We consider the new divisor 46 and the new remainder 21,and apply the division lemma to get
46 = 21 x 2 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8156 and 657 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(46,21) = HCF(113,46) = HCF(272,113) = HCF(657,272) = HCF(8156,657) .
