HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 669, 471 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 669, 471 is 3 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 669, 471 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 669, 471 is 3.
HCF(669, 471) = 3
HCF of 669, 471 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 669, 471 is 3.
Highest Common Factor of 669,471 is 3
Step 1: Since 669 > 471, we apply the division lemma to 669 and 471, to get
669 = 471 x 1 + 198
Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 198 and 471, to get
471 = 198 x 2 + 75
Step 3: We consider the new divisor 198 and the new remainder 75, and apply the division lemma to get
198 = 75 x 2 + 48
We consider the new divisor 75 and the new remainder 48,and apply the division lemma to get
75 = 48 x 1 + 27
We consider the new divisor 48 and the new remainder 27,and apply the division lemma to get
48 = 27 x 1 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 669 and 471 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(48,27) = HCF(75,48) = HCF(198,75) = HCF(471,198) = HCF(669,471) .
