HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 865, 867 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 865, 867 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 436, 865, 867 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 436, 865, 867 is 1.
HCF(436, 865, 867) = 1
HCF of 436, 865, 867 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 865, 867 is 1.
Highest Common Factor of 436,865,867 is 1
Step 1: Since 865 > 436, we apply the division lemma to 865 and 436, to get
865 = 436 x 1 + 429
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 429 and 436, to get
436 = 429 x 1 + 7
Step 3: We consider the new divisor 429 and the new remainder 7, and apply the division lemma to get
429 = 7 x 61 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 436 and 865 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(429,7) = HCF(436,429) = HCF(865,436) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 867 > 1, we apply the division lemma to 867 and 1, to get
867 = 1 x 867 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 867 is 1
Notice that 1 = HCF(867,1) .
