HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 672, 457 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 672, 457 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 672, 457 is 1.
HCF(672, 457) = 1
HCF of 672, 457 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 672, 457 is 1.
Highest Common Factor of 672,457 is 1
Step 1: Since 672 > 457, we apply the division lemma to 672 and 457, to get
672 = 457 x 1 + 215
Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 215 and 457, to get
457 = 215 x 2 + 27
Step 3: We consider the new divisor 215 and the new remainder 27, and apply the division lemma to get
215 = 27 x 7 + 26
We consider the new divisor 27 and the new remainder 26,and apply the division lemma to get
27 = 26 x 1 + 1
We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 672 and 457 is 1
Notice that 1 = HCF(26,1) = HCF(27,26) = HCF(215,27) = HCF(457,215) = HCF(672,457) .
