HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 339, 198 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 339, 198 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 868, 339, 198 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 868, 339, 198 is 1.
HCF(868, 339, 198) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 339, 198 is 1.
Step 1: Since 868 > 339, we apply the division lemma to 868 and 339, to get
868 = 339 x 2 + 190
Step 2: Since the reminder 339 ≠ 0, we apply division lemma to 190 and 339, to get
339 = 190 x 1 + 149
Step 3: We consider the new divisor 190 and the new remainder 149, and apply the division lemma to get
190 = 149 x 1 + 41
We consider the new divisor 149 and the new remainder 41,and apply the division lemma to get
149 = 41 x 3 + 26
We consider the new divisor 41 and the new remainder 26,and apply the division lemma to get
41 = 26 x 1 + 15
We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get
26 = 15 x 1 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 868 and 339 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(41,26) = HCF(149,41) = HCF(190,149) = HCF(339,190) = HCF(868,339) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 198 > 1, we apply the division lemma to 198 and 1, to get
198 = 1 x 198 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 198 is 1
Notice that 1 = HCF(198,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
