HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 156, 867, 115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 156, 867, 115 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 156, 867, 115 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 156, 867, 115 is 1.
HCF(156, 867, 115) = 1
HCF of 156, 867, 115 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 156, 867, 115 is 1.
Highest Common Factor of 156,867,115 is 1
Step 1: Since 867 > 156, we apply the division lemma to 867 and 156, to get
867 = 156 x 5 + 87
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 87 and 156, to get
156 = 87 x 1 + 69
Step 3: We consider the new divisor 87 and the new remainder 69, and apply the division lemma to get
87 = 69 x 1 + 18
We consider the new divisor 69 and the new remainder 18,and apply the division lemma to get
69 = 18 x 3 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 156 and 867 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(69,18) = HCF(87,69) = HCF(156,87) = HCF(867,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 115 > 3, we apply the division lemma to 115 and 3, to get
115 = 3 x 38 + 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 115 is 1
Notice that 1 = HCF(3,1) = HCF(115,3) .
