HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 164, 946, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 477, 164, 946, 686 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 477, 164, 946, 686 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 477, 164, 946, 686 is 1.
HCF(477, 164, 946, 686) = 1
HCF of 477, 164, 946, 686 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 477, 164, 946, 686 is 1.
Highest Common Factor of 477,164,946,686 is 1
Step 1: Since 477 > 164, we apply the division lemma to 477 and 164, to get
477 = 164 x 2 + 149
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 149 and 164, to get
164 = 149 x 1 + 15
Step 3: We consider the new divisor 149 and the new remainder 15, and apply the division lemma to get
149 = 15 x 9 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 477 and 164 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(149,15) = HCF(164,149) = HCF(477,164) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 946 > 1, we apply the division lemma to 946 and 1, to get
946 = 1 x 946 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 946 is 1
Notice that 1 = HCF(946,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get
686 = 1 x 686 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1
Notice that 1 = HCF(686,1) .
