HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 469, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 469, 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 469, 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 469, 657 is 1.
HCF(469, 657) = 1
HCF of 469, 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 469, 657 is 1.
Highest Common Factor of 469,657 is 1
Step 1: Since 657 > 469, we apply the division lemma to 657 and 469, to get
657 = 469 x 1 + 188
Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 188 and 469, to get
469 = 188 x 2 + 93
Step 3: We consider the new divisor 188 and the new remainder 93, and apply the division lemma to get
188 = 93 x 2 + 2
We consider the new divisor 93 and the new remainder 2,and apply the division lemma to get
93 = 2 x 46 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 469 and 657 is 1
Notice that 1 = HCF(2,1) = HCF(93,2) = HCF(188,93) = HCF(469,188) = HCF(657,469) .
