HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 936, 164, 618, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 936, 164, 618, 71 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 936, 164, 618, 71 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 936, 164, 618, 71 is 1.
HCF(936, 164, 618, 71) = 1
HCF of 936, 164, 618, 71 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 936, 164, 618, 71 is 1.
Highest Common Factor of 936,164,618,71 is 1
Step 1: Since 936 > 164, we apply the division lemma to 936 and 164, to get
936 = 164 x 5 + 116
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 116 and 164, to get
164 = 116 x 1 + 48
Step 3: We consider the new divisor 116 and the new remainder 48, and apply the division lemma to get
116 = 48 x 2 + 20
We consider the new divisor 48 and the new remainder 20,and apply the division lemma to get
48 = 20 x 2 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 936 and 164 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(48,20) = HCF(116,48) = HCF(164,116) = HCF(936,164) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 618 > 4, we apply the division lemma to 618 and 4, to get
618 = 4 x 154 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 618 is 2
Notice that 2 = HCF(4,2) = HCF(618,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 2, we apply the division lemma to 71 and 2, to get
71 = 2 x 35 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 71 is 1
Notice that 1 = HCF(2,1) = HCF(71,2) .
