HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 946, 465 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 865, 946, 465 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, 946, 465 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, 946, 465 is 1.
HCF(865, 946, 465) = 1
HCF of 865, 946, 465 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, 946, 465 is 1.
Highest Common Factor of 865,946,465 is 1
Step 1: Since 946 > 865, we apply the division lemma to 946 and 865, to get
946 = 865 x 1 + 81
Step 2: Since the reminder 865 ≠ 0, we apply division lemma to 81 and 865, to get
865 = 81 x 10 + 55
Step 3: We consider the new divisor 81 and the new remainder 55, and apply the division lemma to get
81 = 55 x 1 + 26
We consider the new divisor 55 and the new remainder 26,and apply the division lemma to get
55 = 26 x 2 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 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 865 and 946 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(55,26) = HCF(81,55) = HCF(865,81) = HCF(946,865) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 465 > 1, we apply the division lemma to 465 and 1, to get
465 = 1 x 465 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 465 is 1
Notice that 1 = HCF(465,1) .
