HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 206, 16, 291 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 538, 206, 16, 291 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 538, 206, 16, 291 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 538, 206, 16, 291 is 1.
HCF(538, 206, 16, 291) = 1
HCF of 538, 206, 16, 291 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 538, 206, 16, 291 is 1.
Highest Common Factor of 538,206,16,291 is 1
Step 1: Since 538 > 206, we apply the division lemma to 538 and 206, to get
538 = 206 x 2 + 126
Step 2: Since the reminder 206 ≠ 0, we apply division lemma to 126 and 206, to get
206 = 126 x 1 + 80
Step 3: We consider the new divisor 126 and the new remainder 80, and apply the division lemma to get
126 = 80 x 1 + 46
We consider the new divisor 80 and the new remainder 46,and apply the division lemma to get
80 = 46 x 1 + 34
We consider the new divisor 46 and the new remainder 34,and apply the division lemma to get
46 = 34 x 1 + 12
We consider the new divisor 34 and the new remainder 12,and apply the division lemma to get
34 = 12 x 2 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 538 and 206 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(34,12) = HCF(46,34) = HCF(80,46) = HCF(126,80) = HCF(206,126) = HCF(538,206) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 16 > 2, we apply the division lemma to 16 and 2, to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 16 is 2
Notice that 2 = HCF(16,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 291 > 2, we apply the division lemma to 291 and 2, to get
291 = 2 x 145 + 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 291 is 1
Notice that 1 = HCF(2,1) = HCF(291,2) .
