HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 269, 861, 231, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 269, 861, 231, 87 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 269, 861, 231, 87 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 269, 861, 231, 87 is 1.
HCF(269, 861, 231, 87) = 1
HCF of 269, 861, 231, 87 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 269, 861, 231, 87 is 1.
Highest Common Factor of 269,861,231,87 is 1
Step 1: Since 861 > 269, we apply the division lemma to 861 and 269, to get
861 = 269 x 3 + 54
Step 2: Since the reminder 269 ≠ 0, we apply division lemma to 54 and 269, to get
269 = 54 x 4 + 53
Step 3: We consider the new divisor 54 and the new remainder 53, and apply the division lemma to get
54 = 53 x 1 + 1
We consider the new divisor 53 and the new remainder 1, and apply the division lemma to get
53 = 1 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 269 and 861 is 1
Notice that 1 = HCF(53,1) = HCF(54,53) = HCF(269,54) = HCF(861,269) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 231 > 1, we apply the division lemma to 231 and 1, to get
231 = 1 x 231 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 231 is 1
Notice that 1 = HCF(231,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get
87 = 1 x 87 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1
Notice that 1 = HCF(87,1) .
