HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 266, 469 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 865, 266, 469 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 865, 266, 469 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 865, 266, 469 is 1.
HCF(865, 266, 469) = 1
HCF of 865, 266, 469 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 865, 266, 469 is 1.
Highest Common Factor of 865,266,469 is 1
Step 1: Since 865 > 266, we apply the division lemma to 865 and 266, to get
865 = 266 x 3 + 67
Step 2: Since the reminder 266 ≠ 0, we apply division lemma to 67 and 266, to get
266 = 67 x 3 + 65
Step 3: We consider the new divisor 67 and the new remainder 65, and apply the division lemma to get
67 = 65 x 1 + 2
We consider the new divisor 65 and the new remainder 2,and apply the division lemma to get
65 = 2 x 32 + 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 865 and 266 is 1
Notice that 1 = HCF(2,1) = HCF(65,2) = HCF(67,65) = HCF(266,67) = HCF(865,266) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 469 > 1, we apply the division lemma to 469 and 1, to get
469 = 1 x 469 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 469 is 1
Notice that 1 = HCF(469,1) .
