HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 137, 216, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 137, 216, 326 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 137, 216, 326 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 137, 216, 326 is 1.
HCF(137, 216, 326) = 1
HCF of 137, 216, 326 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 137, 216, 326 is 1.
Highest Common Factor of 137,216,326 is 1
Step 1: Since 216 > 137, we apply the division lemma to 216 and 137, to get
216 = 137 x 1 + 79
Step 2: Since the reminder 137 ≠ 0, we apply division lemma to 79 and 137, to get
137 = 79 x 1 + 58
Step 3: We consider the new divisor 79 and the new remainder 58, and apply the division lemma to get
79 = 58 x 1 + 21
We consider the new divisor 58 and the new remainder 21,and apply the division lemma to get
58 = 21 x 2 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 137 and 216 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(58,21) = HCF(79,58) = HCF(137,79) = HCF(216,137) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 326 > 1, we apply the division lemma to 326 and 1, to get
326 = 1 x 326 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 326 is 1
Notice that 1 = HCF(326,1) .
