HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 239, 868 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 239, 868 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 615, 239, 868 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 615, 239, 868 is 1.
HCF(615, 239, 868) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 239, 868 is 1.
Step 1: Since 615 > 239, we apply the division lemma to 615 and 239, to get
615 = 239 x 2 + 137
Step 2: Since the reminder 239 ≠ 0, we apply division lemma to 137 and 239, to get
239 = 137 x 1 + 102
Step 3: We consider the new divisor 137 and the new remainder 102, and apply the division lemma to get
137 = 102 x 1 + 35
We consider the new divisor 102 and the new remainder 35,and apply the division lemma to get
102 = 35 x 2 + 32
We consider the new divisor 35 and the new remainder 32,and apply the division lemma to get
35 = 32 x 1 + 3
We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get
32 = 3 x 10 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 615 and 239 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(35,32) = HCF(102,35) = HCF(137,102) = HCF(239,137) = HCF(615,239) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 868 > 1, we apply the division lemma to 868 and 1, to get
868 = 1 x 868 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 868 is 1
Notice that 1 = HCF(868,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
