HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 807, 981, 602 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 217, 807, 981, 602 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 217, 807, 981, 602 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 217, 807, 981, 602 is 1.
HCF(217, 807, 981, 602) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 217, 807, 981, 602 is 1.
Step 1: Since 807 > 217, we apply the division lemma to 807 and 217, to get
807 = 217 x 3 + 156
Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 156 and 217, to get
217 = 156 x 1 + 61
Step 3: We consider the new divisor 156 and the new remainder 61, and apply the division lemma to get
156 = 61 x 2 + 34
We consider the new divisor 61 and the new remainder 34,and apply the division lemma to get
61 = 34 x 1 + 27
We consider the new divisor 34 and the new remainder 27,and apply the division lemma to get
34 = 27 x 1 + 7
We consider the new divisor 27 and the new remainder 7,and apply the division lemma to get
27 = 7 x 3 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 217 and 807 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(27,7) = HCF(34,27) = HCF(61,34) = HCF(156,61) = HCF(217,156) = HCF(807,217) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 981 > 1, we apply the division lemma to 981 and 1, to get
981 = 1 x 981 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 981 is 1
Notice that 1 = HCF(981,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 602 > 1, we apply the division lemma to 602 and 1, to get
602 = 1 x 602 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 602 is 1
Notice that 1 = HCF(602,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
