HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 674, 477 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 674, 477 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 674, 477 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 674, 477 is 1.
HCF(674, 477) = 1
HCF of 674, 477 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 674, 477 is 1.
Highest Common Factor of 674,477 is 1
Step 1: Since 674 > 477, we apply the division lemma to 674 and 477, to get
674 = 477 x 1 + 197
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 197 and 477, to get
477 = 197 x 2 + 83
Step 3: We consider the new divisor 197 and the new remainder 83, and apply the division lemma to get
197 = 83 x 2 + 31
We consider the new divisor 83 and the new remainder 31,and apply the division lemma to get
83 = 31 x 2 + 21
We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get
31 = 21 x 1 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 674 and 477 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(83,31) = HCF(197,83) = HCF(477,197) = HCF(674,477) .
