HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 612, 213, 109 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 612, 213, 109 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 612, 213, 109 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 612, 213, 109 is 1.
HCF(612, 213, 109) = 1
HCF of 612, 213, 109 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 612, 213, 109 is 1.
Highest Common Factor of 612,213,109 is 1
Step 1: Since 612 > 213, we apply the division lemma to 612 and 213, to get
612 = 213 x 2 + 186
Step 2: Since the reminder 213 ≠ 0, we apply division lemma to 186 and 213, to get
213 = 186 x 1 + 27
Step 3: We consider the new divisor 186 and the new remainder 27, and apply the division lemma to get
186 = 27 x 6 + 24
We consider the new divisor 27 and the new remainder 24,and apply the division lemma to get
27 = 24 x 1 + 3
We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 612 and 213 is 3
Notice that 3 = HCF(24,3) = HCF(27,24) = HCF(186,27) = HCF(213,186) = HCF(612,213) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 109 > 3, we apply the division lemma to 109 and 3, to get
109 = 3 x 36 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 109 is 1
Notice that 1 = HCF(3,1) = HCF(109,3) .
